| Abstract(in English) | We developed a software-execution framework for scalable increase of execution speed and low-power consumption based on an octo-core chip multiprocessor named RP2 and an automatic multigrain-parallelizing compiler named OSCAR. Keys to improvement of the performance are reduction of a communication overhead with parallelized tasks and frequent shutdown to waiting cores. For this framework, we developed two schemes: data mapping and timely-power gating. Measurement of the performance for the conventional framework and our proposed framework showed that normalized execution speedup becomes 5.00 when secure AAC-LC encoding is processed in 8-parallel execution. Moreover, applying our timely-power-gating scheme improves power efficiency by 10%. |
