Description |
---|---|---|
wr_dma_read_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. |
wr_dma_address_o[63:0] |
Output |
Specifies the address for the data to be read from a memory component in the Avalon-MM address space . |
wr_dma_read_data_i[255:0] |
Input |
Specifies the completion data that the Write DMA module writes to the PCIe address space. |
wr_dma_burst_count_o[4:0] |
Output |
Specifies the burst count in 256-bit words. |
wr_dma_wait_request_i |
Input |
When asserted, indicates that the memory is not ready to be read. |
wr_dma_read_data_valid_i |
