| Abstract(in English) | Currently, multicore processors are becoming ubiquitous in various computing domains, namely consumer electronics such as games, car navigation systems and mobile phones, PCs, and supercomputers. This paper describes parallelization of media processing programs written in restricted C language by OSCAR multigrain parallelizing compiler and SMP processing performance on RP1 4-core SH-4A (SH-X3) multicore processor developed by Renesas Technology Corp. and Hitachi, Ltd. based on standard OSCAR multicore memory architecture as a part of NEDO "Research and Development of Multicore Technology for Real Time Consumer Electronics Project". Performance evaluation shows OSCAR compiler achieved 3.34 times speedup using 4 cores against using 1 core for AAC audio encoder. |
