摘要
相关算法是一种可靠性很高的匹配算法,在信号处理中有很重要的应用。但由于计算量大,严重影响了该算法的实时运行。提出了利用行列递推来实现相关算法的快速计算,并针对实时处理的需要,结合TMS320C6711DSP的特点,研究了相关算法的几种DSP优化实现方法。实验证明,经过优化后,算法的匹配速度得到了很大提高。
Correlation algorithm is a reliable match algorithm, which is widely used in digital signal processing, but the large calculating demand badly weaken the real-time performance of match algorithm. A faster calculation of line-by-line recursion for correlation algorithm is presented. Based on the features of TMS320C6711, the means of software optimization for DSP is proposed to improve real-time performance. The results show that the match speed is greatly improved by optimization.
