This paper introduces the JPEG2000 still image compression technology in the TI TMS320DM642 DSP Implementation process on wavelet compression technology is the core algorithm to improve the structure of the hardware features of the process structure, read and write the specific code and bus improvements, such as was described in detail . The improved software system, for 1 024 × 768 pixel image size, data storage space only 6 KB, allows limited resources to run the DSP chip JPEG2000 image compression technology encoding speed is not improved relative to the improvement of the l2 ~ 2O-fold, again and again to be 3/s compression ratio for O. 5 bit/p, the peak signal to noise ratio can be achieved 3O.
