Aiming at the problem of parallel signal processing and large consumption of transmission resources,the high-speed RapidIO bus is used to fully interconnect multi-core DSP,and the data is shared through memory mapping.Eight cores can transmit and process data in parallel respectively.The RapidIO block with lightweight header has high transmission rate,few data copies and high efficiency.It has been proved that the data throughput has been greatly improved,the transmission delay has been reduced,and the problems such as long compilation time,difficult debugging,and high price in parallel computing of traditional FPGA devices have been solved.It can be extended to radar signal pulse compression,SAR image processing,distributed intelligent cloud computing and other fields.
