摘　　要：本文介绍的实时图像处理系统以双片ＴｅｘａｓＩｎｓｔｒｕｍｅｎｔｓ公司的通用数字信号处理器ＤＳＰ（ＤｉｇｉｔａｌＳｉｇｎａｌＰｒｏｃｅｓｓｏｒ）ＴＭＳ３２０Ｃ４０为核心。电路采用可变结构帧存形式，与两片ＴＭＳ３２０Ｃ４０灵活的外部接口及强大的通信能力相结合，使系统可方便地组织成ＳＩＭＤ、ＭＩＭＤ等并行处理结构及流水处理结构；在不增加硬件电路的情况下，解决了图像分块并行处理时交界处不应有的变异问题。In this paper,a realtimeimage processing system based on two-chip general purpose DSP TMS320C40 of Texas Instruments was introduced.The frame store was reconfigurable.This,combined with the flexible interface and powerful communication capability of TMS320C40 ,made the system be easily configured as SIMD,MIMD parallel and pipeline structures.The distortion of image processed by several elements was geniously avoided without any additional circuits.
