Paper Abstract

A scheme to realize static image and video code and decode based on TI DSP chip TMS320C6416 was proposed in this paper, and a reliable image transmission system was developed. According to the application demand, the software has six major modules: (1) initialization of DSP chip and other hardware; (2) video acquisition and input control program; (3) serial port communicating program; (4) RAM storage and communicating program that applies and releases the token-ring; (5) video reconstruct and output control; (6) the major parts of the software, encoding and decoding program, in which wavelet was applied first, then run length coding and Huffman coding were carried out, the image or video could had balance resolution and better visual effect by adaptive processing, in the decoding parts, the reverse operation were executed. After the system line up debugging was carried out, a satisfying result was reached: the comparatively high compression rate, preferable image quality and relatively real-time result.
