Applications Using the TMS320C6000 Enhanced DMA
David Bell ABSTRACT The enhanced direct memory access (EDMA) controller is the backbone of the two-level cache architecture for the TMS320C6000 DSPs. The EDMA performs: Digital Signal Processing Solutions
cache servicing host-port servicing user-programmable data transfers
Through proper configuration, EDMA channels can be set up to operate continuously without requiring CPU intervention or reprogramming. This allows the CPU to use its MIPS for data processing, while the EDMA handles data management in the background. Either 16 or 64 channels, plus a Quick DMA (QDMA) register set, are programmable to perform data transfers during CPU operation. EDMA channels and QDMA register sets are useful t
