The article, summarizing the attributes of DSP chip and the theory of the image compression, puts an emphasis on describing the image compression system based on TMS320VC5409 DSP chip. Additionally, based on the image compression system, a fast DCT image compression method and an adaptive JPEG quantification way are proposed. The realization and application of the image compression system show that the proposed method runs faster and gets higher quality of image than the standard JPEG compression method at the same compression rate.
