摘要
实时信号分析系统要求具有处理大量数据的能力,以保证系统的实时性。基于某重点工程项目,采用Altera公司的新型现场可编程门阵列(FPGA)和AD公司的新型ADSP-TS101S系统,对于高速实时并行处理进行了研究,设计实现了一种新的高速数据并行分析系统,并介绍了DSP的操作流程。该系统能对输入信号的频谱进行分析,并已测试成功,应用于某雷达监测系统。构建的FPGA+DSP处理系统的结构灵活,有较强的通用性,并适于模块化设计,同时其开发周期较短,系统易于维护和扩展。
The real-time signal processing system should be capable of processing large quantities of data so that it is a real-time system in the true sense. Based on a key project, this paper studies the high-speed digital parallel processing by using Altera Inc＇ s FPGA and AD Inc＇ s DSP--ADSP-TS 101S and proposes a new high-speed digital parallel analyzing system. It also introduces the operation flow of DSP. This system, which has been tested successfully, can analyze the frequency spectrum of the input signal and is used for a radar inspecting system. The processing system of FPGA＋DSP is, because of its flexible structure, universal and fit for modularization design. Due to its short development period, it is easy to maintain and exoand.
