一种基于FPGA的多DSP数据交换方法

摘要

随着各种信号系统复杂度的不断提高,对信号处理的要求也逐步提高,多DSP并行处理的技术应运而生并成为信号处理领域研究的热点.构建了一套多DSP的数据并行处理系统,讨论了基于FPGA的高速串行数据通信的有效方法,实现了多DSP系统内任意两片DSP间的串行数据通信,提供了一种多DSP系统中灵活的数据交换方式.%The signal systems become more complicated, so the request for the velocity and volume of signal processing is becoming more strict The parallel processing is an effective solution and becomes the hot point of signal processing research. The paper proposes a parallel processing system based on the multiple DSPs, analyzes an effective method of the high-speed serial communication based on FPGA, provides a flexible high-speed data exchanging approach, At last,the high-speed data communication between any two chips is realized.
