Abstract
This paper describes parallelization of the JasPer reference software for JPEG-2000 and presents results from simulation, and from hardware execution on a multicore processor where speedups of more than 2 are obtained with 4 processors. Loop fusion is applied before parallelization to increase workload granularity. Results from profiling and cache behavior analysis are presented to establish the expected speedup and to gain further insight into execution characteristics.
