图像无损压缩算法的DSP实现及优化

With the development of the digital image communication technology, a large number of image data’s storage and transmission greatly restricted the development of image communication, and become a “bottleneck” problem of it. The purpose of lossless image compression is to reduce the amount of data used to represent the image without any information loss, so the original image can be recovered correctly when decoding. Huffman coding is a basic arithmetic of many image coding standards, but it has a shortcoming of slow coding and decoding. This paper gives a fast Huffman compress and decompresses method based on the traditional Huffman coding method, and Implementation the method on the TI DSP Integrated development environment CCS, and optimize it according to the hardware. The experimental result shows that the time of compression or decompression is achieve the desired objectives, and it guarantees the real-time transmission and coding of digital image.
