摘要
为满足实时信号处理对高速卷积的要求,本文在对卷积的算法进行优化的基础上,提出以高速DSP单片机TMS320C25为CPU的信号处理器的组成及其编程方法。其运算速度比用FORTRAN程序在IBM PC机上运行高若干数量级。以序列长度N=64为例,速度将提高0(10~4)。0(10~4)表示四个数量级。
For suiting to the needs of high speed of convolution in real-time digital signal processing, the paper analysed and optimized the algorithms of convolution, and then, made a hardware structure with TMS320C25 and programming technique. As a result, the operating speed of convolution had been gained by O(104) as compared to IBM PC with FORTRAN programs.
