Clash.Explicit.RAM

Description

RAM primitives with a combinational read port.

Synopsis

RAM synchronized to an arbitrary clock

asyncRam Source #

Arguments

:: (Enum addr, HasCallStack, KnownDomain wdom, KnownDomain rdom) 
=> Clock wdom

Clock to which to synchronize the write port of the RAM

-> Clock rdom

Clock to which the read address signal, r, is synchronized to

-> Enable wdom

Global enable

-> SNat n

Size n of the RAM

-> Signal rdom addr

Read address r

-> Signal wdom (Maybe (addr, a))

(write address w, value to write)

-> Signal rdom a

Value of the RAM at address r

Create a RAM with space for n elements

Additional helpful information:

Arguments

:: forall wdom rdom n a. (KnownNat n, HasCallStack, KnownDomain wdom, KnownDomain rdom) 
=> Clock wdom

Clock to which to synchronize the write port of the RAM

-> Clock rdom

Clock to which the read address signal, r, is synchronized

-> Enable wdom

Global enable

-> Signal rdom (Unsigned n)

Read address r

-> Signal wdom (Maybe (Unsigned n, a))

(write address w, value to write)

-> Signal rdom a
