| Abstract: | In spite of its many advantages such as higher compression rate,multi-resolution format and progressive transmission shows decoding,JPEG2000 has not been widely used because of its high cost of implementation since it was proposed.This paper presents a solution to the high-speed and real-time hardware of multi-level IDWT based on FPGA in view of the kernel processing module——inverse discrete wavelet transform （IDWT） in JPEG2000 decoding system.Simulation shows that this solution can meet the requirement for real-time processing of continuous input of data.Besides,the system has the advantages of less consumption and lower cost. |
