Clash.Prelude

Description

Clash is a functional hardware description language that borrows both its syntax and semantics from the functional programming language Haskell. The merits of using a functional language to describe hardware comes from the fact that combinational circuits can be directly modeled as mathematical functions and that functional languages lend themselves very well at describing and (de-)composing mathematical functions.

This package provides:

  • Prelude library containing datatypes and functions for circuit design

To use the library:

  • Import Clash.Prelude; by default clock and reset lines are implicitly routed for all the components found in Clash.Prelude. You can read more about implicit clock and reset lines in Clash.Signal
  • Alternatively, if you want to explicitly route clock and reset ports, for more straightforward multi-clock designs, you can import the Clash.Explicit.Prelude module. Note that you should not import Clash.Prelude and Clash.Explicit.Prelude at the same time as they have overlapping definitions.

For now, Clash.Prelude is also the best starting point for exploring the library. A preliminary version of a tutorial can be found in Clash.Tutorial. Some circuit examples can be found in Clash.Examples.

Synopsis

Creating synchronous sequential circuits

mealy Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX s) 
=> (s -> i -> (s, o))

Transfer function in mealy machine form: state -> input -> (newstate,output)

-> s

Initial state

-> Signal dom i -> Signal dom o

Synchronous sequential function with input and output matching that of the mealy machine

Create a synchronous function from a combinational function describing a mealy machine

macT
  :: Int        -- Current state
  -> (Int,Int)  -- Input
  -> (Int,Int)  -- (Updated state, output)
macT s (x,y) = (s',s)
  where
    s' = x * y + s

mac :: HiddenClockResetEnable dom  => Signal dom (Int, Int) -> Signal dom Int
mac = mealy macT 0
>>> simulate @System mac [(0,0),(1,1),(2,2),(3,3),(4,4)]
[0,0,1,5,14...
...

Synchronous sequential functions can be composed just like their combinational counterpart:

dualMac
  :: HiddenClockResetEnable dom
  => (Signal dom Int, Signal dom Int)
  -> (Signal dom Int, Signal dom Int)
  -> Signal dom Int
dualMac (a,b) (x,y) = s1 + s2
  where
    s1 = mealy macT 0 (bundle (a,x))
    s2 = mealy macT 0 (bundle (b,y))

mealyB Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX s, Bundle i, Bundle o) 
=> (s -> i -> (s, o))

Transfer function in mealy machine form: state -> input -> (newstate,output)

-> s

Initial state

-> Unbundled dom i -> Unbundled dom o

Synchronous sequential function with input and output matching that of the mealy machine

A version of mealy that does automatic Bundleing

Given a function f of type:

f :: Int -> (Bool, Int) -> (Int, (Int, Bool))

When we want to make compositions of f in g using mealy, we have to write:

g a b c = (b1,b2,i2)
  where
    (i1,b1) = unbundle (mealy f 0 (bundle (a,b)))
    (i2,b2) = unbundle (mealy f 3 (bundle (c,i1)))

Using mealyB however we can write:

g a b c = (b1,b2,i2)
  where
    (i1,b1) = mealyB f 0 (a,b)
    (i2,b2) = mealyB f 3 (c,i1)

(<^>) Source #

-> Unbundled dom i -> Unbundled dom o

Synchronous sequential function with input and output matching that of the mealy machine

Infix version of mealyB

moore Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX s) 
=> (s -> i -> s)

Transfer function in moore machine form: state -> input -> newstate

-> (s -> o)

Output function in moore machine form: state -> output

-> s

Initial state

-> Signal dom i -> Signal dom o

Synchronous sequential function with input and output matching that of the moore machine

Create a synchronous function from a combinational function describing a moore machine

macT
  :: Int        -- Current state
  -> (Int,Int)  -- Input
  -> Int        -- Updated state
macT s (x,y) = x * y + s

mac
  :: HiddenClockResetEnable dom
  => Signal dom (Int, Int)
  -> Signal dom Int
mac = moore mac id 0
>>> simulate @System mac [(0,0),(1,1),(2,2),(3,3),(4,4)]
[0,0,1,5,14,30,...
...

Synchronous sequential functions can be composed just like their combinational counterpart:

dualMac
  :: HiddenClockResetEnable dom
  => (Signal dom Int, Signal dom Int)
  -> (Signal dom Int, Signal dom Int)
  -> Signal dom Int
dualMac (a,b) (x,y) = s1 + s2
  where
    s1 = moore macT id 0 (bundle (a,x))
    s2 = moore macT id 0 (bundle (b,y))

mooreB Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX s, Bundle i, Bundle o) 
=> (s -> i -> s)

Transfer function in moore machine form: state -> input -> newstate

-> (s -> o)

Output function in moore machine form: state -> output

-> s

Initial state

-> Unbundled dom i -> Unbundled dom o

A version of moore that does automatic Bundleing

Given a functions t and o of types:

t :: Int -> (Bool, Int) -> Int
o :: Int -> (Int, Bool)

When we want to make compositions of t and o in g using moore, we have to write:

g a b c = (b1,b2,i2)
  where
    (i1,b1) = unbundle (moore t o 0 (bundle (a,b)))
    (i2,b2) = unbundle (moore t o 3 (bundle (c,i1)))

Using mooreB however we can write:

g a b c = (b1,b2,i2)
  where
    (i1,b1) = mooreB t o 0 (a,b)
    (i2,b2) = mooreB t o 3 (c,i1)

registerB :: (HiddenClockResetEnable dom, NFDataX a, Bundle a) => a -> Unbundled dom a -> Unbundled dom a infixr 3 Source #

Create a register function for product-type like signals (e.g. '(Signal a, Signal b)')

rP :: HiddenClockResetEnable dom
   => (Signal dom Int, Signal dom Int)
   -> (Signal dom Int, Signal dom Int)
rP = registerB (8,8)
>>> simulateB @System rP [(1,1),(2,2),(3,3)] :: [(Int,Int)]
[(8,8),(1,1),(2,2),(3,3)...
...

createMemBlob Source #

Arguments

:: forall a f. (Foldable f, BitPack a) 
=> String

Name of the binding to generate

-> Maybe Bit

Value to map don't care bits to. Nothing means throwing an error on don't care bits.

-> f a

The content for the MemBlob

-> DecsQ 

Create a MemBlob binding from a list of values

Since this uses Template Haskell, nothing in the arguments given to createMemBlob can refer to something defined in the same module.

Example

Expand
createMemBlob "content" Nothing [15 :: Unsigned 8 .. 17]

ram clk en = blockRamBlob clk en content

The Maybe datatype has don't care bits, where the actual value does not matter. But the bits need a defined value in the memory. Either 0 or 1 can be used, and both are valid representations of the data.

>>> import qualified Prelude as P
>>> let es = [ Nothing, Just (7 :: Unsigned 8), Just 8 ]
>>> :{
createMemBlob "content0" (Just 0) es
createMemBlob "content1" (Just 1) es
x = 1
:}
>>> let pr = mapM_ (putStrLn . show)
>>> pr $ P.map pack es
0b0_...._....
0b1_0000_0111
0b1_0000_1000
>>> pr $ unpackMemBlob content0

>>> :{

x = 1
:}

<interactive>:...: error:
    packBVs: cannot convert don't care values. Please specify a mapping to a definite value.

Note how we hinted to clashi that our multi-line command was a list of declarations by including a dummy declaration x = 1. Without this trick, clashi would expect an expression and the Template Haskell would not work.

memBlobTH Source #

Arguments

:: forall a f. (Foldable f, BitPack a) 
=> Maybe Bit

Value to map don't care bits to. Nothing means throwing an error on don't care bits.

-> f a

Create a MemBlob from a list of values

Since this uses Template Haskell, nothing in the arguments given to memBlobTH can refer to something defined in the same module.

Example

Any value that is being written on a particular port is also the value that will be read on that port, i.e. the same-port read/write behavior is: WriteFirst. For mixed-port read/write, when port A writes to the address port B reads from, the output of port B is undefined, and vice versa.

isRising Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX a, Bounded a, Eq a) 
=> a

Starting value

-> Signal dom a 
-> Signal dom Bool 

Give a pulse when the Signal goes from minBound to maxBound

isFalling Source #

Arguments

:: (HiddenClockResetEnable dom, NFDataX a, Bounded a, Eq a) 
=> a

Starting value

-> Signal dom a 
-> Signal dom Bool 

Give a pulse when the Signal goes from maxBound to minBound

riseEvery :: HiddenClockResetEnable dom => SNat n -> Signal dom Bool Source #

Give a pulse every n clock cycles. This is a useful helper function when combined with functions like regEn or mux, in order to delay a register by a known amount.

To be precise: the given signal will be False for the next n-1 cycles, followed by a single True value:

>>> Prelude.last (sampleN @System 1025 (riseEvery d1024)) == True
True
>>> Prelude.or (sampleN @System 1024 (riseEvery d1024)) == False
True

For example, to update a counter once every 10 million cycles:

counter = regEn 0 (riseEvery (SNat :: SNat 10000000)) (counter + 1)

oscillate :: HiddenClockResetEnable dom => Bool -> SNat n -> Signal dom Bool Source #

Oscillate a Bool for a given number of cycles. This is a convenient function when combined with something like regEn, as it allows you to easily hold a register value for a given number of cycles. The input Bool determines what the initial value is.

To oscillate on an interval of 5 cycles:

>>> sampleN @System 11 (oscillate False d5)
[False,False,False,False,False,False,True,True,True,True,True]

To oscillate between True and False:

>>> sampleN @System 11 (oscillate False d1)
[False,False,True,False,True,False,True,False,True,False,True]

An alternative definition for the above could be:

>>> let osc' = register False (not <$> osc')
>>> sampleN @System 200 (oscillate False d1) == sampleN @System 200 osc'
True

Tracing

Simple

traceSignal1 Source #

Arguments

:: (BitPack a, NFDataX a, Typeable a) 
=> String

Name of signal in the VCD output

-> Signal dom a

Signal to trace

-> Signal dom a 

Trace a single signal. Will emit an error if a signal with the same name was previously registered.

NB associates the traced signal with a clock period of 1, which results in incorrect VCD files when working with circuits that have multiple clocks. Use traceSignal when working with circuits that have multiple clocks.

traceVecSignal1 Source #

Arguments

:: (KnownNat n, BitPack a, NFDataX a, Typeable a) 
=> String

Name of signal in debugging output. Will be appended by _0, _1, ..., _n.

-> Signal dom (Vec (n + 1) a)

Signal to trace

-> Signal dom (Vec (n + 1) a) 

Trace a single vector signal: each element in the vector will show up as a different trace. If the trace name already exists, this function will emit an error.

NB associates the traced signal with a clock period of 1, which results in incorrect VCD files when working with circuits that have multiple clocks. Use traceSignal when working with circuits that have multiple clocks.

Tracing in a multi-clock environment

traceSignal Source #

Arguments

:: forall dom a. (KnownDomain dom, BitPack a, NFDataX a, Typeable a) 
=> String

Name of signal in the VCD output

-> Signal dom a

Signal to trace

-> Signal dom a 

Trace a single signal. Will emit an error if a signal with the same name was previously registered.

NB Works correctly when creating VCD files from traced signal in multi-clock circuits. However traceSignal1 might be more convenient to use when the domain of your circuit is polymorphic.

traceVecSignal Source #

Arguments

:: forall dom a n. (KnownDomain dom, KnownNat n, BitPack a, NFDataX a, Typeable a) 
=> String

Name of signal in debugging output. Will be appended by _0, _1, ..., _n.

-> Signal dom (Vec (n + 1) a)

Signal to trace

-> Signal dom (Vec (n + 1) a) 

Trace a single vector signal: each element in the vector will show up as a different trace. If the trace name already exists, this function will emit an error.

NB Works correctly when creating VCD files from traced signal in multi-clock circuits. However traceSignal1 might be more convenient to use when the domain of your circuit is polymorphic.

VCD dump functions

dumpVCD Source #

Arguments

:: NFDataX a 
=> (Int, Int)

(offset, number of samples)

-> Signal dom a

(One of) the outputs of the circuit containing the traces

-> [String]

The names of the traces you definitely want to be dumped in the VCD file

-> IO (Either String Text) 

Produce a four-state VCD (Value Change Dump) according to IEEE 1364-{1995,2001}. This function fails if a trace name contains either non-printable or non-VCD characters.

Due to lazy evaluation, the created VCD files might not contain all the traces you were expecting. You therefore have to provide a list of names you definately want to be dumped in the VCD file.

For example:

vcd <- dumpVCD (0, 100) cntrOut ["main", "sub"]

Evaluates cntrOut long enough in order for to guarantee that the main, and sub traces end up in the generated VCD file.

data Enable dom Source #

A signal of booleans, indicating whether a component is enabled. No special meaning is implied, it's up to the component itself to decide how to respond to its enable line. It is used throughout Clash as a global enable signal.

data Signal (dom :: Domain) a Source #

Clash has synchronous Signals in the form of:

Signal (dom :: Domain) a

Where a is the type of the value of the Signal, for example Int or Bool, and dom is the clock- (and reset-) domain to which the memory elements manipulating these Signals belong.

The type-parameter, dom, is of the kind Domain - a simple string. That string refers to a single synthesis domain. A synthesis domain describes the behavior of certain aspects of memory elements in it.

  • NB: "Bad things"™ happen when you actually use a clock period of 0, so do not do that!
  • NB: You should be judicious using a clock with period of 1 as you can never create a clock that goes any faster!
  • NB: For the best compatibility make sure your period is divisible by 2, because some VHDL simulators don't support fractions of picoseconds.
  • NB: Whether System has good defaults depends on your target platform. Check out IntelSystem and XilinxSystem too!

Signals have the type role

>>> :i Signal
type role Signal nominal representational
...

as it is safe to coerce the underlying value of a signal, but not safe to coerce a signal between different synthesis domains.

See the module documentation of Clash.Signal for more information about domains.

vSystem :: VDomainConfiguration Source #

Convenience value to allow easy "subclassing" of System domain. Should be used in combination with createDomain. For example, if you just want to change the period but leave all other settings intact use:

createDomain vSystem{vName="System10", vPeriod=10}

vIntelSystem :: VDomainConfiguration Source #

Convenience value to allow easy "subclassing" of XilinxSystem domain. Should be used in combination with createDomain. For example, if you just want to change the period but leave all other settings intact use:

createDomain vXilinxSystem{vName="Xilinx10", vPeriod=10}

vDomain :: SDomainConfiguration dom conf -> VDomainConfiguration Source #

Convert SDomainConfiguration to VDomainConfiguration. Should be used in combination with createDomain only.

createDomain :: VDomainConfiguration -> Q [Dec] Source #

Convenience method to express new domains in terms of others.

createDomain (knownVDomain @System){vName="System10", vPeriod=10}

This duplicates the settings in the System domain, replaces the name and period, and creates an instance for it. As most users often want to update the system domain, a shortcut is available in the form:

createDomain vSystem{vName="System10", vPeriod=10}

The function will create two extra identifiers. The first:

type System10 = ..

You can use that as the dom to Clocks/Resets/Enables/Signals. For example: Signal System10 Int. Additionally, it will create a VDomainConfiguration that you can use in later calls to createDomain:

vSystem10 = knownVDomain @System10

It will also make System10 an instance of KnownDomain.

If either identifier is already in scope it will not be generated a second time. Note: This can be useful for example when documenting a new domain:

-- | Here is some documentation for CustomDomain
type CustomDomain = ("CustomDomain" :: Domain)

-- | Here is some documentation for vCustomDomain
createDomain vSystem{vName="CustomDomain"}

class Bundle a where Source #

Isomorphism between a Signal of a product type (e.g. a tuple) and a product type of Signals.

Instances of Bundle must satisfy the following laws:

bundle . unbundle = id
unbundle . bundle = id

By default, bundle and unbundle, are defined as the identity, that is, writing:

data D = A | B

instance Bundle D

is the same as:

data D = A | B

instance Bundle D where
  type Unbundled clk D = Signal clk D
  bundle   s = s
  unbundle s = s

For custom product types you'll have to write the instance manually:

data Pair a b = MkPair { getA :: a, getB :: b }

instance Bundle (Pair a b) where
  type Unbundled dom (Pair a b) = Pair (Signal dom a) (Signal dom b)

  -- bundle :: Pair (Signal dom a) (Signal dom b) -> Signal dom (Pair a b)
  bundle   (MkPair as bs) = MkPair $ as * bs

  -- unbundle :: Signal dom (Pair a b) -> Pair (Signal dom a) (Signal dom b)
  unbundle pairs = MkPair (getA $ pairs) (getB $ pairs)

data TaggedEmptyTuple (dom :: Domain) Source #

Helper type to emulate the "old" behavior of Bundle's unit instance. I.e., the instance for Bundle () used to be defined as:

class Bundle () where
  bundle   :: () -> Signal dom ()
  unbundle :: Signal dom () -> ()

In order to have sensible type inference, the Bundle class specifies that the argument type of bundle should uniquely identify the result type, and vice versa for unbundle. The type signatures in the snippet above don't though, as () doesn't uniquely map to a specific domain. In other words, domain should occur in both the argument and result of both functions.

TaggedEmptyTuple tackles this by carrying the domain in its type. The bundle and unbundle instance now looks like:

class Bundle EmptyTuple where
  bundle   :: TaggedEmptyTuple dom -> Signal dom EmptyTuple
  unbundle :: Signal dom EmptyTuple -> TaggedEmptyTuple dom

dom is now mentioned both the argument and result for both bundle and unbundle.

resetSynchronizer :: forall dom. KnownDomain dom => Clock dom -> Reset dom -> Reset dom Source #

The resetSynchronizer will synchronize an incoming reset according to whether the domain is synchronous or asynchronous.

For asynchronous resets this synchronizer ensures the reset will only be de-asserted synchronously but it can still be asserted asynchronously. The reset assert is immediate, but reset de-assertion is delayed by two cycles.

Normally, asynchronous resets can be both asynchronously asserted and de-asserted. Asynchronous de-assertion can induce meta-stability in the component which is being reset. To ensure this doesn't happen, resetSynchronizer ensures that de-assertion of a reset happens synchronously. Assertion of the reset remains asynchronous.

Note that asynchronous assertion does not induce meta-stability in the component whose reset is asserted. However, when a component "A" in another clock or reset domain depends on the value of a component "B" being reset, then asynchronous assertion of the reset of component "B" can induce meta-stability in component "A". To prevent this from happening you need to use a proper synchronizer, for example one of the synchronizers in Clash.Explicit.Synchronizer.

For synchronous resets this function ensures that the reset is asserted and de-asserted synchronously. Both the assertion and de-assertion of the reset are delayed by two cycles.

Example 1

Expand

The circuit below detects a rising bit (i.e., a transition from 0 to 1) in a given argument. It takes a reset that is not synchronized to any of the other incoming signals and synchronizes it using resetSynchronizer.

topEntity
  :: Clock  System
  -> Reset  System
  -> Signal System Bit
  -> Signal System (BitVector 8)
topEntity clk asyncRst key1 =
  withClockResetEnable clk rst enableGen leds
 where
  rst   = resetSynchronizer clk asyncRst
  key1R = isRising 1 key1
  leds  = mealy blinkerT (1, False, 0) key1R

Example 2

Expand

Similar to Example 1 this circuit detects a rising bit (i.e., a transition from 0 to 1) in a given argument. It takes a clock that is not stable yet and a reset singal that is not synchronized to any other signals. It stabalizes the clock and then synchronizes the reset signal.

topEntity
  :: Clock  System
  -> Reset  System
  -> Signal System Bit
  -> Signal System (BitVector 8)
topEntity clk rst key1 =
    let  (pllOut,pllStable) = altpll (SSymbol @"altpll50") clk rst
         rstSync            = resetSynchronizer pllOut (unsafeToHighPolarity pllStable)
    in   exposeClockResetEnable leds pllOut rstSync enableGen
  where
    key1R  = isRising 1 key1
    leds   = mealy blinkerT (1, False, 0) key1R

resetGlitchFilter Source #

Arguments

:: forall dom glitchlessPeriod n. (KnownDomain dom, glitchlessPeriod ~ (n + 1)) 
=> SNat glitchlessPeriod

Consider a reset signal to be properly asserted after having seen the reset asserted for glitchlessPeriod cycles straight.

-> Clock dom 
-> Reset dom 
-> Reset dom 

Filter glitches from reset signals by only triggering a reset after it has been asserted for glitchlessPeriod cycles. It will then stay asserted for as long as the given reset was asserted consecutively.

If synthesized on a domain with initial values, resetGlitchFilter will output an asserted reset for glitchlessPeriod cycles (plus any cycles added by the given reset). If initial values can't be used, it will only output defined reset values after glitchlessPeriod cycles.

Example with test bench

Expand

A common usage is with a test bench using outputVerifier.

NB: Since this uses assert, when using clashi, read the note at Clash.Explicit.Testbench.

import Clash.Prelude
import Clash.Explicit.Testbench

topEntity
  :: Signal System Int
  -> Signal System Int
topEntity = id

testBench
  :: Signal System Bool
testBench = done
 where
  testInput = stimuliGenerator clk rst $(listToVecTH [1 :: Int .. 10])
  expectedOutput =
    outputVerifier' clk rst $(listToVecTH $ [1 :: Int .. 9] <> [42])
  done = expectedOutput $ topEntity testInput
  clk = tbSystemClockGen (not <$> done)
  rst = systemResetGen
> runUntil id testBench


cycle(<Clock: System>): 10, outputVerifier
expected value: 42, not equal to actual value: 10
Signal sampled for 11 cycles until value True

When you need to verify multiple test benches, the following invocations come in handy:

> mapM_ (runUntil id) [ testBenchA, testBenchB ]

or when the test benches are in different clock domains:

testBenchA :: Signal DomA Bool
testBenchB :: Signal DomB Bool
> sequence_ [ runUntil id testBenchA, runUntil id testBenchB ]

KnownNat n => Generic (Vec n a) Source #

In many cases, this Generic instance only allows generic functions/instances over vectors of at least size 1, due to the n-1 in the Rep (Vec n a) definition.

We'll have to wait for things like https://ryanglscott.github.io/2018/02/11/how-to-derive-generic-for-some-gadts/ before we can work around this limitation

foldl :: (b -> a -> b) -> b -> Vec n a -> b Source #

foldl, applied to a binary operator, a starting value (typically the left-identity of the operator), and a vector, reduces the vector using the binary operator, from left to right:

foldl f z (x1 :> x2 :> ... :> xn :> Nil) == (...((z `f` x1) `f` x2) `f`...) `f` xn
foldl f z Nil                            == z
>>> foldl (/) 1 (5 :> 4 :> 3 :> 2 :> Nil)
8.333333333333333e-3

"foldl f z xs" corresponds to the following circuit layout:

NB: "foldl f z xs" produces a linear structure, which has a depth, or delay, of O(length xs). Use fold if your binary operator f is associative, as "fold f xs" produces a structure with a depth of O(log_2(length xs)).

foldr :: (a -> b -> b) -> b -> Vec n a -> b Source #

foldr, applied to a binary operator, a starting value (typically the right-identity of the operator), and a vector, reduces the vector using the binary operator, from right to left:

foldr r z Nil                             == z

NB: "foldl1 f z xs" produces a linear structure, which has a depth, or delay, of O(length xs). Use fold if your binary operator f is associative, as "fold f xs" produces a structure with a depth of O(log_2(length xs)).

fold :: forall n a. (a -> a -> a) -> Vec (n + 1) a -> a Source #

fold is a variant of foldr1 and foldl1, but instead of reducing from right to left, or left to right, it reduces a vector using a tree-like structure. The depth, or delay, of the structure produced by "fold f xs", is hence O(log_2(length xs)), and not O(length xs).

NB: The binary operator "f" in "fold f xs" must be associative.

fold f (x1 :> x2 :> ... :> xn1 :> xn :> Nil) == ((x1 `f` x2) `f` ...) `f` (... `f` (xn1 `f` xn))
fold f (x1 :> Nil)                           == x1
fold f Nil                                   == TYPE ERROR

        rights = tail xs
        sorted = zipWith (flip compareSwapL) rights lefts
:}

Example usage

For example:

-- Bubble sort for 1 iteration
sortV xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith compareSwapL lefts rights

-- Compare and swap
compareSwapL a b = if a < b then (a,b)
                            else (b,a)

Will not terminate because zipWith is too strict in its second argument.

In this case, adding lazyV on zipWiths second argument:

sortVL xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith compareSwapL (lazyV lefts) rights

Results in a successful computation:

>>> sortVL (4 :> 1 :> 2 :> 3 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

NB: There is also a solution using flip, but it slightly obfuscates the meaning of the code:

sortV_flip xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith (flip compareSwapL) rights lefts
>>> sortV_flip (4 :> 1 :> 2 :> 3 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

>>> type instance Apply (Append m a) l = Vec (l + m) a
>>> let append' xs ys = dfold (Proxy :: Proxy (Append m a)) (const (:>)) ys xs

Example usage

Using lists, we can define append (a.k.a. Data.List.++) in terms of Data.List.foldr:

>>> import qualified Data.List
>>> let append xs ys = Data.List.foldr (:) ys xs
>>> append [1,2] [3,4]
[1,2,3,4]

However, when we try to do the same for Vec, by defining append' in terms of Clash.Sized.Vector.foldr:

append' xs ys = foldr (:>) ys xs

we get a type error:

>>> let append' xs ys = foldr (:>) ys xs

<interactive>:...
    • Occurs check: cannot construct the infinite type: ... ~ ... + 1
      Expected type: a -> Vec ... a -> Vec ... a
        Actual type: a -> Vec ... a -> Vec (... + 1) a
    • In the first argument of ‘foldr’, namely ‘(:>)’
      In the expression: foldr (:>) ys xs
      In an equation for ‘append'’: append' xs ys = foldr (:>) ys xs
    • Relevant bindings include
        ys :: Vec ... a (bound at ...)
        append' :: Vec n a -> Vec ... a -> Vec ... a
          (bound at ...)

The reason is that the type of foldr is:

>>> :t foldr
foldr :: (a -> b -> b) -> b -> Vec n a -> b

While the type of (:>) is:

>>> :t (:>)
(:>) :: a -> Vec n a -> Vec (n + 1) a

We thus need a fold function that can handle the growing vector type: dfold. Compared to foldr, dfold takes an extra parameter, called the motive, that allows the folded function to have an argument and result type that depends on the current length of the vector. Using dfold, we can now correctly define append':

import Data.Singletons
import Data.Proxy

data Append (m :: Nat) (a :: Type) (f :: TyFun Nat Type) :: Type
type instance Apply (Append m a) l = Vec (l + m) a

append' xs ys = dfold (Proxy :: Proxy (Append m a)) (const (:>)) ys xs

We now see that append' has the appropriate type:

>>> :t append'
append' :: KnownNat k => Vec k a -> Vec m a -> Vec (k + m) a

And that it works:

>>> append' (1 :> 2 :> Nil) (3 :> 4 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

NB: "dfold m f z xs" creates a linear structure, which has a depth, or delay, of O(length xs). Look at dtfold for a dependently typed fold that produces a structure with a depth of O(log_2(length xs)).

dtfold Source #

Arguments

The motive

-> (a -> p @@ 0)

Function to apply to every element

-> (forall l. SNat l -> (p @@ l) -> (p @@ l) -> p @@ (l + 1))

Function to combine results.

NB: The SNat l indicates the depth/height of the node in the tree that is created by applying this function. The leafs of the tree have depth/height 0, and the root of the tree has height k.

-> Vec (2 ^ k) a

Vector to fold over.

NB: Must have a length that is a power of 2.

-> p @@ k 

A combination of dfold and fold: a dependently typed fold that reduces a vector in a tree-like structure.

                                 (bv2v bv)
:}

Example usage

As an example of when you might want to use dtfold we will build a population counter: a circuit that counts the number of bits set to '1' in a BitVector. Given a vector of n bits, we only need we need a data type that can represent the number n: Index (n+1). Index k has a range of [0 .. k-1] (using ceil(log2(k)) bits), hence we need Index n+1. As an initial attempt we will use sum, because it gives a nice (log2(n)) tree-structure of adders:

populationCount :: (KnownNat (n+1), KnownNat (n+2))
                => BitVector (n+1) -> Index (n+2)
populationCount = sum . map fromIntegral . bv2v

The "problem" with this description is that all adders have the same bit-width, i.e. all adders are of the type:

(+) :: Index (n+2) -> Index (n+2) -> Index (n+2).

This is a "problem" because we could have a more efficient structure: one where each layer of adders is precisely wide enough to count the number of bits at that layer. That is, at height d we want the adder to be of type:

Index ((2^d)+1) -> Index ((2^d)+1) -> Index ((2^(d+1))+1)

We have such an adder in the form of the add function, as defined in the instance ExtendingNum instance of Index. However, we cannot simply use fold to create a tree-structure of addes:

>>> :{
let populationCount' :: (KnownNat (n+1), KnownNat (n+2))
                     => BitVector (n+1) -> Index (n+2)
    populationCount' = fold add . map fromIntegral . bv2v
:}

<interactive>:...
    • Couldn't match type ‘((n + 2) + (n + 2)) - 1’ with ‘n + 2’
      Expected type: Index (n + 2) -> Index (n + 2) -> Index (n + 2)
        Actual type: Index (n + 2)
                     -> Index (n + 2) -> AResult (Index (n + 2)) (Index (n + 2))
    • In the first argument of ‘fold’, namely ‘add’
      In the first argument of ‘(.)’, namely ‘fold add’
      In the expression: fold add . map fromIntegral . bv2v
    • Relevant bindings include
        populationCount' :: BitVector (n + 1) -> Index (n + 2)
          (bound at ...)

because fold expects a function of type "a -> a -> a", i.e. a function where the arguments and result all have exactly the same type.

In order to accommodate the type of our add, where the result is larger than the arguments, we must use a dependently typed fold in the form of dtfold:

{-# LANGUAGE UndecidableInstances #-}
import Data.Singletons
import Data.Proxy

data IIndex (f :: TyFun Nat Type) :: Type
type instance Apply IIndex l = Index ((2^l)+1)

populationCount' :: (KnownNat k, KnownNat (2^k))
                 => BitVector (2^k) -> Index ((2^k)+1)
populationCount' bv = dtfold (Proxy @IIndex)
                             fromIntegral
                             (\_ x y -> add x y)
                             (bv2v bv)

And we can test that it works:

>>> :t populationCount' (7 :: BitVector 16)
populationCount' (7 :: BitVector 16) :: Index 17
>>> populationCount' (7 :: BitVector 16)
3

Some final remarks:

  • By using dtfold instead of fold, we had to restrict our BitVector argument to have bit-width that is a power of 2.
  • Even though our original populationCount function specified a structure where all adders had the same width. Most VHDL/(System)Verilog synthesis tools will create a more efficient circuit, i.e. one where the adders have an increasing bit-width for every layer, from the VHDL/(System)Verilog produced by the Clash compiler.

NB: The depth, or delay, of the structure produced by "dtfold m f g xs" is O(log_2(length xs)).

KnownNat n => Generic (Vec n a) Source #

In many cases, this Generic instance only allows generic functions/instances over vectors of at least size 1, due to the n-1 in the Rep (Vec n a) definition.

Template Haskell

class Lift (t :: TYPE r) where #

A Lift instance can have any of its values turned into a Template Haskell expression. This is needed when a value used within a Template Haskell quotation is bound outside the Oxford brackets ([| ... |] or [|| ... ||]) but not at the top level. As an example:

add1 :: Int -> Q (TExp Int)
add1 x = [|| x + 1 ||]

Template Haskell has no way of knowing what value x will take on at splice-time, so it requires the type of x to be an instance of Lift.

A Lift instance must satisfy $(lift x) ≡ x and $$(liftTyped x) ≡ x for all x, where $(...) and $$(...) are Template Haskell splices. It is additionally expected that lift x ≡ unTypeQ (liftTyped x).

Lift instances can be derived automatically by use of the -XDeriveLift GHC language extension:

{-# LANGUAGE DeriveLift #-}
module Foo where

import Language.Haskell.TH.Syntax

data Bar a = Bar1 a (Bar a) | Bar2 String
  deriving Lift

Type classes

Clash

class NFDataX a => AutoReg a Source #

autoReg is a "smart" version of register. It does two things:

  1. It splits product types over their fields. For example, given a 3-tuple, the corresponding HDL will end up with three instances of a register (or more if the three fields can be split up similarly).
  2. Given a data type where a constructor indicates (parts) of the data will (not) be updated a given cycle, it will split the data in two parts. The first part will contain the "always interesting" parts (the constructor bits). The second holds the "potentially uninteresting" data (the rest). Both parts will be stored in separate registers. The register holding the "potentially uninteresting" part will only be enabled if the constructor bits indicate they're interesting.

The most important example of this is Maybe. Consider Maybe (Signed 16); when viewed as bits, a Nothing would look like:

>>> pack @(Maybe (Signed 16)) Nothing
0b0_...._...._...._....

and Just

>>> pack @(Maybe (Signed 16)) (Just 3)
0b1_0000_0000_0000_0011

In the first case, Nothing, we don't particularly care about updating the register holding the Signed 16 field, as they'll be unknown anyway. We can therefore deassert its enable line.

Making Clash lay it out like this increases the chances of synthesis tools clock gating the registers, saving energy.

This version of autoReg will split the given data type up recursively. For example, given a :: Maybe (Maybe Int, Maybe Int), a total of five registers will be rendered. Both the "interesting" and "uninteresting" enable lines of the inner Maybe types will be controlled by the outer one, in addition to the inner parts controlling their "uninteresting" parts as described in (2).

The default implementation is just register. If you don't need or want the special features of AutoReg, you can use that by writing an empty instance.

data MyDataType = ...
instance AutoReg MyDataType

If you have a product type you can use deriveAutoReg to derive an instance.

Implicit version of autoReg

deriveAutoReg :: Name -> DecsQ Source #

Automatically derives an AutoReg instance for a product type

Usage:

data Pair a b = MkPair { getA :: a, getB :: b } deriving (Generic, NFDataX)
data Tup3 a b c = MkTup3 { getAB :: Pair a b, getC :: c } deriving (Generic, NFDataX)
deriveAutoReg ''Pair
deriveAutoReg ''Tup3

NB: Because of the way template haskell works the order here matters, if you try to deriveAutoReg ''Tup3 before Pair it will complain about missing an instance AutoReg (Pair a b).

Haskell Prelude

Clash.Prelude re-exports most of the Haskell Prelude with the exception of those functions that the Clash API defines to work on Vec from Clash.Sized.Vector instead of on lists as the Haskell Prelude does. In addition, for the odd and even functions a type class called Parity is available at Clash.Class.Parity.
