The EDMA3 is a high-performance, multi-channel module for the TMS320C64x+ DSP that allows you to program a wide variety of transfer geometries and sequences. In addition, it interacts with the switch central resource (SCR) fabric to compete for bus and read/write access resources. The EDMA3 prioritization scheme is summarized and various program registers are introduced in this application report. Additionally, the report explains how to use the EDMA3 debug capability to view its internal operation; this is demonstrated on a test program running on the TMS320C6455 DSP starter kit (DSK).
