The application of EDMA in TD-LTE-A system

Combined TMS320C6455DSP and FPGA data acquisition platform, this paper describes the C6455 DSP Enhanced Direct Memory Access (EDMA) hardware architecture and configuration methods, focusing on the EDMA applied in two ways, both of which increase the transmission DSP data transfer speed, enhanced the DSP processing power to meet the physical layer of TD-LTEA complex algorithms in real time operations. At present, the technology has been successfully applied in TD-LTE-A RF Conformance Test System.
