3.1. Streaming DMA AFU Memory Map
The streaming DMA register map provides the absolute addresses of all the locations within the unit. These registers are in the host view because only the host can access them.
|Byte Address||Register Name||Span in Bytes||Description|
|0x0000||Streaming DMA AFU DFH||0x40||Device feature header for the streaming DMA AFU. This DFH points to 0x100 as the next DFH offset.|
|0x0040||2:1 Multiplexer||0x8||Routes the streaming data from either the pattern generator or the Decimator to the S2M BBB.|
Performs loopback testing that programmatically filters out
|0x0050||1:2 De-multiplexer||0x8||Routes the streaming data to pattern checker and generator or perform loopback testing between the M2S and S2M DMAs.|
|0x0100||M2S DMA BBB||0x100||Memory-to-stream DMA BBB. The M2S DMA BBB points to 0x100 as the next DFH offset.|
|0x0200||S2M DMA BBB||0x100||Stream-to-memory DMA BBB. The S2M DMA BBB DFH points to 0x100 as the next DFH offset.|
|0x0300||NULL DFH||0x40||Null device feature header terminating the DFH linked list.|
|0x1000||Pattern Checker Memory Slave||0x1000||Pattern checker memory populated by the host application.|
|0x2000||Pattern Generator Memory Slave||0x1000||Pattern generator memory populated by the host application|
|0x3000||Pattern Checker CSR Slave||0x10||Pattern checker control and status registers|
|0x3010||Pattern Generator CSR Slave||0x10||Pattern generator control and status registers.|
