Design and Implementation of High-Speed Signal Processing System Based on TMS320C6701

介绍一种基于 TI高性能浮点 DSP- TMS32 0 C6 70 1的高速信号处理系统。该系统完全采用软件的方法实现对中频调频信号的采集、传输、谱分析、解调等一系列的处理 ,并将处理结果通过串口上传给计算机。为了解决 DSP总线冲突的问题 ,该系统采用了两级 DMA来实现采集数据的存储。试验证明 ,该信号处理板能够在 16 0 MHz下完成调频信号的采集、传输和处理 。

A high speed signal processing system based on TI high performance floating point DSP TMS320C6701 is introduced in this paper.The board realizes a series of processing of IF FM signals,such as data acquisition,data transmission,spectrum analysis and demodulation,then results can be transferred to PC using serial port.To solve the DSP bus collision,two level DMA transmission scheme is used.It is proved by experiments that this signal processing board works very well and stable.
