CLaSH.Signal.Bundle

The Product/Signal isomorphism

Documentation

class Bundle a where

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

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

Minimal complete definition

Nothing

Associated Types

type Unbundled' clk a

Methods

bundle' :: SClock clk -> Unbundled' clk a -> Signal' clk a

Example:

bundle' :: (Signal' clk a, Signal' clk b) -> Signal' clk (a,b)

However:

bundle' :: Signal' clk Bit -> Signal' clk Bit

unbundle' :: SClock clk -> Signal' clk a -> Unbundled' clk a

Example:

unbundle' :: Signal' clk (a,b) -> (Signal' clk a, Signal' clk b)

However:

unbundle' :: Signal' clk Bit -> Signal' clk Bit
