DMA register values used in
Figure 2
:
DMACConfig = 0x01
DMACCxSrcAddr = 0xe0000000; EMC_CS0
DMACCxDestAddr = 0xe0000040; EMC_CS0
DMACCxLLI = 0x0
DMACCxControl = 0x0c480004; Dest & Src addrs increment, Dest & Src 32-bit; Dburst
& Sburst size 1; transfer size 4
DMACCxConfig = 0x01
EMCStaticConfig0 = 0x00000082; 32-bit width, Byte lane state 1
Results of this behavior:
1. DMA reads from an external memory will have lower performance than a software
read loop. The source read burst of two, to get one transfer, will significantly increase
the time to complete all transfers in the memory-to-memory DMA, therefore
decreasing the overall throughput possible on the EMC_CSx_N static memory
interface.
2. Potential unintended consequence when the last DMA read accesses the address
beyond the DMA source buffer address in the FPGA or external peripheral chip. This
extra address is the second access during the last DMA source read.
