Description
RAM primitives with a combinational read port.
- asyncRam :: Enum addr => SNat n -> Signal addr -> Signal addr -> Signal Bool -> Signal a -> Signal a
- asyncRamPow2 :: forall n a. (KnownNat (2 ^ n), KnownNat n) => Signal (Unsigned n) -> Signal (Unsigned n) -> Signal Bool -> Signal a -> Signal a
- asyncRam' :: Enum addr => SClock wclk -> SClock rclk -> SNat n -> Signal' wclk addr -> Signal' rclk addr -> Signal' wclk Bool -> Signal' wclk a -> Signal' rclk a
- asyncRamPow2' :: forall wclk rclk n a. (KnownNat n, KnownNat (2 ^ n)) => SClock wclk -> SClock rclk -> Signal' wclk (Unsigned n) -> Signal' rclk (Unsigned n) -> Signal' wclk Bool -> Signal' wclk a -> Signal' rclk a
- asyncRam# :: SClock wclk -> SClock rclk -> SNat n -> Signal' wclk Int -> Signal' rclk Int -> Signal' wclk Bool -> Signal' wclk a -> Signal' rclk a
RAM synchronised to the system clock
Arguments

| => SNat n | Size |
| -> Signal addr | Write address |
| -> Signal addr | Read address |
| -> Signal Bool | Write enable |
| -> Signal a | Value to write (at address |
| -> Signal a | Value of the |
Create a RAM with space for n elements.
- NB: Initial content of the RAM is
undefined
