| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Currently, multicore processors are becoming ubiquitous in various computing domains, namely con- sumer 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. |
