data Unsigned (n :: Nat) Source #

Arbitrary-width unsigned integer represented by n bits

Given n bits, an Unsigned n number has a range of: [0 .. 2^n-1]

  • NB: The usual Haskell method of converting an integral numeric type to another, fromIntegral, is not well suited for Clash as it will go through Integer which is arbitrarily bounded in HDL. Instead use bitCoerce and the Resize class.
  • NB: The Num operators perform wrap-around on overflow. If you want saturation on overflow, check out the SaturatingNum class.
>>> maxBound :: Unsigned 3
7
>>> minBound :: Unsigned 3
0
>>> read (show (maxBound :: Unsigned 3)) :: Unsigned 3
7
>>> 1 + 2 :: Unsigned 3
3
>>> 2 + 6 :: Unsigned 3
0
>>> 1 - 3 :: Unsigned 3
6
>>> 2 * 3 :: Unsigned 3
6
>>> 2 * 4 :: Unsigned 3
0
>>> (2 :: Unsigned 3) `mul` (4 :: Unsigned 3) :: Unsigned 6
8
>>> (2 :: Unsigned 3) `add` (6 :: Unsigned 3) :: Unsigned 4
8
>>> satAdd SatSymmetric 2 6 :: Unsigned 3
7
>>> satSub SatSymmetric 2 3 :: Unsigned 3
0

Unsigned has the type role

>>> :i Unsigned
type role Unsigned nominal
...

as it is not safe to coerce between different width Unsigned. To change the width, use the functions in the Resize class.
