DMA Descriptor Status Bus when Instantiated Separately
Read DMA and Write DMA modules report status to the Descriptor Controller on the RdDmaTx-
Data_o[31:0] or WrDmaTxData_o[31:0] bus when one of the following trigger events occurs:
• A descriptor is activated
• A descriptor completes successfully
The following table shows the mappings of the triggering events to the DMA descriptor status bus:

Done
When asserted, a single DMA descriptor has completed success‐
fully.
[7:0] Descriptor ID The ID of the descriptor whose status is being reported.
Descriptor Controller Interfaces when Instantiated Internally
Read Descriptor Controller Avalon-MM Master Port
The Read Descriptor Controller Avalon-MM master port drives the TX Avalon-MM slave port. This port
drives single dword transactions to the V-Series Avalon-MM DMA for PCIe. The Read Descriptor
Controller uses this port to write descriptor status to the PCIe domain and possibly to MSI when MSI
messages are enabled.

Signal Name Direction Description
RdDCMAddress_o[63:0]
Output Specifies the address for the read data.
RdDCMByteEnable_
o[3:0]
Output Specifies which data bytes are valid.
RdDCMReadDataValid_i
Input When asserted, indicates that the read data is valid.
RdDCMReadData_o[31:0]
Output
Drives the single dword read data.
