Implementation of serial communication on the TMS320DM6437 with McBSP and EDMA

With the TMS320DM6437,this paper discusses the implementation of serial communication based on the chip multi-channel buffered serial port(McBSP) and enhanced direct memory access(EDMA).While the software part uses the McBSP Driver and EDMA low level lriver driver(EDMA LLD) for development instead of using traditional CSL.Finally,it realized the Ping/Pong structure and full-duplex continuous data stream transmission between FPGA and DSP,while using the DSP/BIOS realizes EDMA interrupt,which helps processing the received data.It meets the real-time requirement and the efficiency of data transfer.
