| Abstract: | Based on the real-time video processing system, under the software development environment Code Composer Studio, this paper realized moving target-acquisition and edge-detection on the platform of TMS320C5000 through hardware design and programming code. Focusing on the deficiencies of traditional methods such as long delay and bad real-time capability, this paper utilizes CCS to optimize the key codes in the program, and debugs it in a simulation platform. According to the test result, the execution efficiency of the system is highly enhanced and it meets the requirement of real-time processing. Besides this system combines the merits of the flexibility of software with high-speed of DSP, so it can process the video data in a true meaning of real-time state. |
