设计了一套实时功率谱分析系统，主要用于信号的实时功率谱分析。采用DSP浮点芯片TMS32C6713作为系统的主处理单元，负责进行功率谱分析；FPGA芯片 Spartan xc2s200为主控制单元，并通过CY7C68013 USB芯片与基于LabVIEW的上位机进行通信。为了保证系统的实时性，在DSP中使用了实时操作系统内核DSP／BIOS．它提供了抢占式多线程、硬件抽象、与寄存器配置等功能。分别采用频率为25 Hz、100 Hz的正弦信号对该系统进行标定。

Power spectrum analysis in the modern industry has very important significance and practical application value.A real time power spectrum analysis system was designed, mainly used for real-time signal power spectrum analysis.In this paper, a TI’ s floating-point DSP chip TMS32C6713 was used as main processing unit, responsible for the power spectrum analysis.A Xil-inx’ s FPGA chip Spartan xc2s200 was used as main control unit, and communicated with the LabVIEW-based PC through Cy-press’s USB chip CY7C68013.In order to ensure the real-time of the system, a real-time operating system kernel DSP /BIOS was used.It provides the functions of preemptive multithreading, hardware abstraction, register configuration, and so on.The sinusoid-al signals with the frequency of 25 Hz and 100 Hz were adopted to calibrate the system.
