The CCSDS Image Data Compression standard uses 9/7 integer lifting wavelet transform as the core algorithm,which is simple and easy in hardware design and implementation.This paper designs and implements a 9/7 integer lifting wavelet transform system based on FPGA with internal RAM memory to reduce the demand for storage,and with the line-based column transform method,by which the row transform and column transform are done simultaneously,thereby increasing the speed.Simulation and synthesis results show that the design requires less hardware resources and runs faster.
