摘　　要：提出了在TMS320C6000系列DSP上实现图像积相关算法的软件方案,重点介绍C6701的设计方案.在该方案中使用了Ping Pong存储区交替、基准图与实时图错位存放、按列扫描输入、基准图和实时图分割与填零扩充等技术措施,解决了片内存储区数量少、图像大小随机变化和存取冲突等难题,并人工优化核心汇编语言程序,充分发挥了C6701的并行处理能力,并在此基础上通过比较得出C6201的实现方案.实验证明,对于72×72实时图与320×320基准图的积相关处理,C6701用时1s,C6201用时0.85s.In this paper, a software implementati on of picture product correlation algorithm based on TMS320C6000 DSP is presented. The design based on C6701 is introduced mainly. In order to solve the difficult y of lacking on-chip memory, the random changing of picture size, the conflict ion of loading and storing and so on, the design uses the technologies like Ping -Pong memory alternation, the different starting bank of storage of reference p icture and scan picture, the input of image by scanning of the columns, and the picture splitting and the filling of zeroes. The design also writes an ASM progr am to reach parallel processing ability of C6701. And then, the design based on C6201 is obtained. As to the product correlation process of 72×72 scan picture and 320×320 reference picture, it can be proved that C6701 can spare 1 second w hile C6201 spare 0.85 second.
