31.7.1.5.5. Avalon® -ST Response
This interface is used by the Prefetcher core to retrieve response information from dispatcher’s core upon each transfer completion.
Signal Role | Width | Description |
---|---|---|
Valid | 1 | Avalon® -ST valid control. Prefetcher core expects valid signal to remain high while the bus is being back pressured. |
Ready | 1 | Avalon® -ST ready control. Used by the Prefetcher core to back pressure the external ST response source. |
Data | 256 | Avalon® -ST data bus. Refer to dispatcher’s response source format for ST data definition. Prefetcher core expects data signals to remain constant while the bus is being back pressured. |
Streaming interface (ST) data bus format and definition are similar to the dispatcher’s response source format:
Bits | Signal Information |

[31:0] | Actual bytes transferred [31:0] |
[39:32] | Error [7:0] |
40 | Early termination |
41 | Transfer complete IRQ mask |
[49:42] | Error IRQ mask |
50 | Early termination IRQ mask |
51 | Descriptor buffer full |
[255:52] | Reserved |
