Datatypes
newtype 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 throughInteger
which is arbitrarily bounded in HDL. Instead usebitCoerce
and theResize
class. - NB: The
Num
operators performwrap-around
on overflow. If you want saturation on overflow, check out theSaturatingNum
class.

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.
