Abstract

コンピュータのハードウェアや,ソフトウェアを動的に最適化する「動的システム最適化技術」が注目されている.筆者らはSysteMorphという適応型動的システム最適化技術の概念を用い,その応用システムの研究を行っている.本論文では動的システム最適化技術によって到達可能な性能向上を評価実験によって示す.動的システム最適化技術による性能向上を対象プログラムの最適化前後のクロックサイクル数の比率で定義する.評価実験の結果からVLIW型の加速実行部を持つシステムで高い性能向上が期待できるアプリケーションを示す.

Dynamic optimization technology for a system which dynamically optimizes both software and hardware is gaining attention of computer system researchers. The authors are researching SysteMorph, a feedback directed dynamic and adaptive hardware/instruction set architecture(ISA)/software co-optimization technology. The technology enables to optimize performance, power, and consumption energy for a system dynamically. In this paper the authors describe attainable performance improvement with the SysteMorph technology. Clock cycle counts of benchmark programs by applying the SysteMorph are evaluated using a simulation method. The, performance improvement is shown as a rate of the clock cycle count comparing with unoptimized state. As a conclusion the authors show an application group which can achieve large performance improvement in a system using VLIW acceleration unit.
