Asynchronous ROM
Arguments
| :: (KnownNat n, Enum addr) | |
| => Vec n a | ROM content NB: must be a constant |
| -> addr | Read address |
| -> a | The value of the ROM at address |
An asynchronous/combinational ROM with space for n elements
Additional helpful information:
- See CLaSH.Sized.Fixed and CLaSH.Prelude.BlockRam for ideas on how to use ROMs and RAMs
Arguments
| :: (KnownNat (2 ^ n), KnownNat n) | |
| => Vec (2 ^ n) a | ROM content NB: must be a constant |
| -> Unsigned n | Read address |

An asynchronous/combinational ROM with space for 2^n elements
Additional helpful information:
- See CLaSH.Sized.Fixed and CLaSH.Prelude.BlockRam for ideas on how to use ROMs and RAMs
Synchronous ROM synchronised to the system clock
Arguments
| :: (KnownNat n, KnownNat m) | |
| => Vec n a | ROM content NB: must be a constant |
