Clash.Prelude.ROM

Description

ROMs

Synopsis

Asynchronous ROM

asyncRom Source #

Arguments

:: (KnownNat n, Enum addr) 
=> Vec n a

ROM content

NB: must be a constant

-> addr

Read address rd

-> a

The value of the ROM at address rd

An asynchronous/combinational ROM with space for n elements

Additional helpful information:

asyncRomPow2 Source #

Arguments

:: KnownNat n 
=> Vec (2 ^ n) a

ROM content

NB: must be a constant

-> Unsigned n

Read address rd

-> a

The value of the ROM at address rd

An asynchronous/combinational ROM with space for 2^n elements

Additional helpful information:

Synchronous ROM synchronized to an arbitrary clock

rom Source #

Arguments

:: forall dom n m a. (NFDataX a, KnownNat n, KnownNat m, HiddenClock dom, HiddenEnable dom) 
=> Vec n a

ROM content

NB: must be a constant

-> Signal dom (Unsigned m)

Read address rd

-> Signal dom a

The value of the ROM at address rd

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

  • NB: Read value is delayed by 1 cycle
  • NB: Initial output value is undefined

Additional helpful information:

-> Signal dom a

The value of the ROM at address rd

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

  • NB: Read value is delayed by 1 cycle
