Pipeline Architecture of Forward and Inverse Photo Core Transform for JPEG XR Image Compression

JPEG XR is the new standard of the JPEG community, and it carries the features of its earlier standards, namely the JPEG Baseline and the JPEG 2000. JPEG Baseline and JPEG 2000 have been the most widely used image compression standards owing to their less complexity and lossless compression, respectively. The new JPEG XR is designed to have a better compression level than the JPEG Baseline and reduced computational complexities compared to the JPEG 2000. In this paper, we propose a fully pipelined design architecture of the forward and the inverse photo core transforms used in JPEG XR for image compression. The proposed architecture uses a multiplier-less design, using only add and shift operations for reduced hardware complexity.
