Scheduling strategies for 2D wavelet coding implementations

Wavelet image compression adopted in the JPEG-2000 and MPEG-4 standards offers several advantages over existing methods based on DCT. This paper presents some wavelet codec scheduling strategies obtained by the joint optimization of both the algorithmic part and the architectural features, according to the target system implementation. Results are presented allowing optimization of system performance either for dedicated ASIC design or for embedded software implementations based on software/hardware system resources partitioning. The optimization can target different features such as execution speed, external and internal cache memory performance, power dissipation, number of parallel wavelet filters.
