Research On The Image Compression Platform Based On FPGA And DSP

In the fields of image communication, high performance compression algorithm and real-time coding system are requred.To choose suitable image coding methods and implement platform under different situations is the key to apply to actual systems. The embedded coding based on wavelet transform becomes the main coding technology for its accurate rate control and high quality of reconstruction image.. At the beginning of this paper the progress of image coding technique is presented. After that a new generation image coding algorithm– JPEG2000 is introduced. One emphasis is on the analysis of T2 algorithm and wavelet transform , and the problems coming forth in the hardware realization. A T2 encoder implementation scheme with high performance and low hardware cost is introduced and a wavelet transform algorithm is proposed which meets the real-time coding request well. In the end we discuss the problems on the design of image compression platform and a hardware implement sheme is introduced.
