Abstract :
A high-speed image data compression system Based on high-speed TMS320VC5416DSP is presented; Hardware constitutes and working principle of the digital image processing is introduced. The basic principal of image encoding algorithm of JPEG is summarized and the realization of JPEG on DSP is expounded, especially the realization and optimization of DCT transform is discussed.
