Description |
---|---|---|
WrDMARead_o |
Output |
When asserted, indicates that the Write DMA module is reading data from a memory component in the Avalon-MM address space to write to the PCIe address space. |
WrDmaAddress_o[63:0] |
Output |
Specifies the address for the data to be read from a memory component in the Avalon-MM address space . |
WrDmaReadData_i[127 or 255:0] |
Input |
Specifies the completion data that the Write DMA module writes to the PCIe address space. |
WrDmaBurstCount_o[4:0]or[5:0] |
Output |
Specifies the burst count in 128- or 256-bit words. This bus is 5 bits for the 256-bit interface. It is 6 bits for the 128-bit interface |
WrDmaWaitRequest_i |
Input |
When asserted, indicates that the memory is not ready to be read. |
WrDmaReadDataValid_i |
Input |
When asserted, indicates that WrDmaReadData_i is valid. |
