Changelog for clash-prelude package

0.7.5 May 7th 2015

  • New features:
    • Moore machine combinators

0.7.4 *May 5th 2015

0.7.2 April 20th 2015

0.7.1 March 25th 2015

  • Fixes bugs:
    • Fix laziness bug in Vector.(!!) and Vector.replace

0.7 March 13th 2015

  • New features:

    • Switch types of bundle and bundle', and unbundle and unbundle'.
    • Rename all explicitly clocked versions of Signal functions, to the primed name of the implicitly clocked Signal functions. E.g. cregister is now called register' (where the implicitly clocked function is callled register)
    • Add new instances for DSignal
    • Add experimental antiDelay function for DSignal
    • Generalize lifted functions over Signals (e.g. (.==.))

  • Fixes bugs:

    • Faster versions of Vector.(!!) and Vector.replace

0.6.0.1 November 17th 2014

  • Fixes bugs:
    • Add missing ‘CLaSH.Sized.BitVector’ module to .cabal file.

0.6 November 17th 2014

  • New features:

    • Add Fractional instance for Fixed #9
    • Make indexing/subscript of Vec ascending #4
    • Add separate BitVector type, which has a descending index.
    • Add bit indexing operators, including the index/subscript operator (!).
    • Add bit reduction operators: reduceOr, reduceAnd, reduceOr.
    • Rename BitVector class to BitPack with pack and unpack class methods.
    • Rename Pack class to Bundle with bundle and unbundle class methods.
    • Strip all Vec functions from their v prefix, i.e. vmap -> map.
    • Rename Vec indexing operator from (!) to (!!).
    • Combine Add and Mult class into ExtendingNum class.
    • Add extend and truncate methods to the Resize class.
    • Add SaturatingNum class with saturating numeric operators.
    • Add multitude of lifted Signal operators, i.e. (.==.) :: Eq a => Signal a -> Signal a -> Signal Bool
    • Add CLaSH.Signal.Delayed with functions and data types for delay-annotated signals to support safe synchronisation.
    • Add CLASH.Prelude.DataFlow with functions and data types to create self-synchronising circuits based on data-flow principles.
