Datatypes

data BitVector n

A vector of bits.

• Bit indices are descending
• Num instance performs unsigned arithmetic.

Instances

The functions: enumFrom, enumFromThen, enumFromTo, and enumFromThenTo, are not synthesisable.

Construction

Initialisation

high :: Bit

logic '1'

low :: Bit

logic '0'

bLit :: KnownNat n => String -> Q (TExp (BitVector n))

Create a binary literal

>>> $$(bLit "1001") :: BitVector 4
1001
>>> $$(bLit "1001") :: BitVector 3
001

NB: Will be removed once GHC 7.10 is released which has support for binary literals. Once GHC 7.10 is released you can just write:

>>> 0b1001 :: BitVector 4
1001

Concatenation

(++#) :: KnownNat m => BitVector n -> BitVector m -> BitVector (n + m)

Concatenate two BitVectors
