摘要
卷积是数字信号处理中最基本、最常用的运算之一。本文介绍了利用TMS320C54x系列芯片为基础的DSPLIB库函数中的相关函数和FFT函数来实现数字卷积处理的两种方法,使卷积运算的实现变得容易,并对DSPLIB库函数的使用进行了详细介绍,给出了具体的程序清单和实验结果。
Digital convolution is one of the basic and universal algorithms in digital signal process technology. The paper introduces two methods of digital convolution which use correlation and FFT in DSP library on C54x DSP. They make the realization of digital convolution on C54x DSP easy. In this paper, the DSP library is described in detail and the routines and the results of the experiment are presented.
