188.8.131.52.1. Write Data Mover Avalon® -MM Read Master and Conduit
This interface reads data from the Avalon-MM Read Master interface and writes it to the Host memory.
The wrdm_address_o value is set within the descriptor source address.
|Signal Name||Direction||Description||Platform Designer Interface Name|
Physical function number.
When asserted, indicates that the Avalon® -MM slave is not ready to respond to a request.
waitrequestAllowance = 4
The master can still issue 4 transfers after wrdm_waitrequest_i is asserted.
|wrdm_read_o||O||When asserted, indicates the master is requesting a read transaction.|
|wrdm_address_o[63:0]||O||Specify the byte address regardless of the data width of the master.|
|wrdm_burstcount_o[3:0]||O||The master uses these signals to indicate the number of transfers in each burst.|
|wrdm_byteenable_o[63:0]||O||Specify the valid bytes of wrdm_writedata_o[511:0]. Each bit corresponds to a byte in wrdm_writedata_o[511:0].|
|wrdm_readdatavalid_i||I||Asserted by the slave to indicate that the wrdm_readdata_i[511:0] signals contain valid data in response to a previous read request.|
|wrdm_readdata_i[511:0]||I||Data signals for read transfers.|
The response signals are optional signals that carry the response status.
Note: Because the signals are shared, an interface cannot issue or accept a write response and a read response in the same clock cycle.
The following encodings are available:
