基于TMS320C80的相关和卷积处理的并行实现

Parallel Achievement of Digital Correlation and Convolution Based on TMS320C80

在雷达和声纳等许多信号处理场合，都需要高速、长样本、高精度的数字相关和数字卷积处理，随着并行处理技术和新一代可编程数字信号处理芯片的发展，这种需求可以得到满足。文中利用ＴＩ公司的ＴＭＳ３２０Ｃ８０（简称Ｃ８０）芯片实现了基于“双缓冲”数据传输的、无内存冲突的、零等待通信的长样本并行相关器和并行卷积器，其速度和精度都得到了保证。

Digital correlation and convolution with high speed, high precision and long sample is necessary for radar and sonar research. With the development of new programmable digital signal processing(DSP)chip and parallel processing technique, this need is becoming contented. In this paper, the parallel situation of correlation and convolution is studied, parallel algorithms based on double buffer model without memory accessing interfere and lingering communication are proposed and realized based on TMS320C80. Some experiments show that the algorithms are of universal significance.
