Abstract

This paper presents a bi-mode, high performance Discrete Wavelet Transform-based image compression core for future spacecrafts and micro-satellites. The hardware solution proposed here exploits an optimized CCSDS IDC algorithm and consists of a lossless mode and a lossly mode. The throughput of the core is improved 40 times using parallel architecture and pipeline technique, and a data rate of about 12.5M pixles/s can be sustained at 50MHz for the lossly mode. The experimental results indicate that this core has high performance at coding efficiency, data rate and error containment for both of the two modes.
