Clash.Explicit.ROM

Contents

Description

ROMs

Synopsis

rom :: (KnownNat n, Enum addr) => Clock domain gated -> Vec n a -> Signal domain addr -> Signal domain a
romPow2 :: KnownNat n => Clock domain gated -> Vec (2 ^ n) a -> Signal domain (Unsigned n) -> Signal domain a
rom# :: KnownNat n => Clock domain gated -> Vec n a -> Signal domain Int -> Signal domain a

Synchronous ROM synchronised to an arbitrary clock

Arguments

:: (KnownNat n, Enum addr)
=> Clock domain gated	`Clock` to synchronize to
-> Vec n a	ROM content NB: must be a constant
-> Signal domain addr	Read address `rd`
-> Signal domain a	The value of the ROM at address `rd` from the previous clock cycle

A ROM with a synchronous read port, with space for n elements

Additional helpful information:

See Clash.Sized.Fixed and Clash.Explicit.BlockRam for ideas on how to use ROMs and RAMs

Arguments

:: KnownNat n
=> Clock domain gated	`Clock` to synchronize to
-> Vec (2 ^ n) a	ROM content NB: must be a constant
-> Signal domain (Unsigned n)	Read address `rd`
-> Signal domain a	The value of the ROM at address `rd`

A ROM with a synchronous read port, with space for 2^n elements
