Each transfer is decomposed into one or multiple transactions by the DMA engine. The firmware can define:
- Burst generation for regular or tiled accesses
(SIMCOP_DMA_CHAN_CTRL_i[6] TILERMODE). Additional parameters must
be defined for tiled accesses. See Block Bursts for Tiled
Transfers.
- The maximum burst size (SIMCOP_DMA_CTRL[1:0] MAX_BURST_SIZE). It must be aligned with the interconnect configuration.
- Use of posted or nonposted writes (SIMCOP_DMA_CTRL[3] POSTED_WRITES). It must be aligned with the interconnect configuration. Mainly, in a multichannel system memory, system bursts must be issued nonposted.
