摘要
基于FPGA+DSP的硬件平台广泛应用于通信、雷达及图像等领域的高速数字信号处理系统,其工作的稳定性极为重要。针对一种基于FPGA+DSP的高速数字信号处理系统在实际应用中出现的偶发性故障,在分析系统的工作原理基础上,对SRIO引导过程与故障现象进行研究分析,分层逐次排查诊断,总结故障的原因,并提出3种解决方法,分析比对后,选择较佳方案改良高速数字信号系统。经过反复运行检测,最终解决了偶发性故障,为今后的故障诊断提供了参考思路。
The hardware platform based on FPGA+DSP is widely used in high-speed digital signal processing systems in communication,radar,image and other fields,and its stability is very important.Aiming at the occasional faults in the practical application of a high-speed digital signal processing system based on FPGA+DSP,based on the analysis of the working principle of the system,the SRIO guidance process and fault phenomena are studied and analyzed,and the layered and successive troubleshooting and diagnosis are carried out.This paper summarizes the causes of the fault,puts forward three solutions,selects the better scheme after analysis and comparison,takes measures to improve the high-speed digital signal system,and finally solves the occasional fault after repeated operation and detection,which provides a reference idea for fault diagnosis in the future.
