摘　　要：为了完成图像目标点的检测和确认,同时实现FPGA与DSP之间的通信数据高速传输,文中基于高速DSP芯片TMS320C6455提出了一种数字图像处理系统设计方案。该系统硬件部分用来模拟图像数据输入输出,软件部分基于Code Composer Studio(CCS)平台采用C语言编程实现。通过软件设计和外部存储器接口(EMIF)、增强型直接存储器(EDMA)等底层配置的实现,完成了图像实时处理过程,并实现了FPGA与DSP之间的高速通信。实验结果表明,利用该芯片设计的图像处理系统完全满足设计要求,实时性较好,系统集成度高,该设计方案在数字图像处理领域具有很大的应用价值。To search for the goal points in the digital image and realize the high-speed data communication between FPGA and DSP, a system based on the high-speed DSP-TMS320C6455 was developed. The hardware part is to emulate the input or output data, and C was applied to complete the software part by Code Composer Studio（CCS）.The image processing system was designed and realized by software design and configuring External Memory Interface （EMIF） ,Enhanced DMA （EDMA） and so on, which finished the task of real-time image processing and high-speed communication. From the experimental results, the Image Processing System is reasonable and ideal so that it totally satisfy the needs, it is a real-time system and works efficiently. Above all, the design is useful and can be applied to many other parts of Digital Image Processing.
