Struct MemoryWritePort

Source
pub struct MemoryWritePort {
    pub addr: Value,
    pub data: Value,
    pub mask: Value,
    pub clock: ControlNet,
}
Expand description

A synchronous memory write port.

Asynchronous memory write ports are not currently supported.

Fields§

§addr: Value

The write address, selecting which row(s) to write. The address is always counted in units of the port’s data width. Thus, if the port width is equal to the memory width, the address is equal to the row index. However, for wide ports, the address is implicitly shifted left by log2(port.data.len() / memory.width) bits to obtain the first row index.

The address can have any width. If the address is too short to address all memory rows, so be it — higher rows will be unreachable by this port.

Writes to out-of-bounds addresses do not modify the memory.

§data: Value

The write data. The width must be a power-of-two multiple of the memory width.

§mask: Value

The write mask. Must have the same width as data. On every active clock edge, a 1 enables writing to the memory for the given data bit, 0 prevents writing.

§clock: ControlNet
