| Abstract: | Today, embedded systems which can produce JPEG image, such as digital camera, mobile and so on, realize JPEG compressing encoding of image by ASIC. And this paper expounds a solution to realize JPEG compressing encoding of image by software based on general DSP.The paper depicts the course of the solution, and especially discusses the optimization of DCT transform and Huffman encoding. It is proved by experiments that the solution is facility and high efficiency, and it can be used in practice absolutely. |
