摘要
介绍了一种以FPGA+ADSP为核心、基于PCI总线支持的高性能实时信号采集和处理系统,该系统利用FPGA的高效逻辑功能以及ADSP TS201的高性能数据处理能力,采用链路口通信方式与多线程编程技术实现多路水声信号的采集与处理,同时实现与计算机之间数据的高速传输,具有高速、高精度、高实时分析能力,适合应用于目前国内最新开发的高性能数字声纳中。
A scheme of the high-powered real-time signal acquisition and processing system in which FPGA and DSP acted as core and based on PC bus-mastering is introduced in the paper.Utilizing the high efficiency logic function of FPGA and the powerful data processing capability of ADSP TS201,this system can acquire and process several channels sighal through the Link Ports communication mode and multithreading programing technique,it can realize high-speed data transmission between DSP and computer,this system provided with high speed precison and real-time analysis capability is compatibly applied to the internal newly researched high-powered sonar system.
