摘要
根据实时信号在线检测系统具有较高实时性的要求,提出一种FPGA和DSP相结合的系统优化设计方案,其中,以FPGA作为主控制器,完成系统的全部控制功能及部分数据预处理,DSP作为数据辅处理器,专注于大批量数据的算法实现。分析了该实时处理系统构成的原理与结构,设计了该系统的硬件电路,阐述了各部分的功能实现,并通过FPGA构建可编程片上系统(SOPC)完成系统硬件仿真,同时,完成了系统软件流程的设计。实验证明,系统可以很好的保证多路参数采集、处理、传输与显示的实时性,系统性能得到很好保证。
Aiming at the demands of high real time in real-time signal detection system,a system design that combines FPGA and DSP was introduced in this paper,in which FPGA as the main controller,completing all control functions of the system,DSP as the microprocessor,focusing on the algorithm of the large amount of data.The paper mainly analyzed the principle and structure of the system,studied the hardware structure,detailed the function of each part to achieve,and completed hardware emulation by constructing Programmable System on Chip（SOPC）in FPGA.Meanwhile,it introduced the software flow chart,and completed the acquisition,processing,transmission and display of the parallel realtime signals.Experimental results show that the system has a good real-time.
