Parameter Legal Values Description
Transfer mode Memory To Memory
Memory To Stream
Stream To Memory Configuration to use. For more information about these configurations, see the Memory-to-Memory Configuration section.
Enable bursting on descriptor read host On/Off If this option is on, the descriptor processor block uses Avalon® -MM bursting when fetching descriptors and writing them back in memory. With 32-bit read and write ports, the descriptor processor block can fetch the 256-bit descriptor by performing 8-word burst as opposed to eight individual single-word transactions.
Allow unaligned transfers On/Off If this option is on, the core allows accesses to non-word-aligned addresses. This option doesn’t apply for burst transfers.

Unaligned transfers require extra logic that may negatively impact system performance.

Enable burst transfers On/Off Turning on this option enables burst reads and writes.
Read burstcount signal width 1–16 The width of the read burstcount signal. This value determines the maximum burst read size.
Write burstcount signal width 1–16 The width of the write burstcount signal. This value determines the maximum burst write size.
Data width 8, 16, 32, 64 The data width in bits for the Avalon® -MM read and write ports.
Source error width 0–7 The width of the error signal for the Avalon® -ST source port.
Sink error width 0 – 7 The width of the error signal for the Avalon® -ST sink port.
Data transfer FIFO depth 2, 4, 8, 16, 32, 64 The depth of the internal data FIFO in memory-to-memory configurations with burst transfers disabled.

The SG-DMA controller core should be given a higher priority (lower IRQ value) than most of the components in a system to ensure high throughput.
