Abstract

本研究では,シングルプロセッサ用 ISS を拡張し,マルチプロセッサ RTOS に対応したコシミュレータを実現した.本コシミュレータでは,複数の ISS とハードウェアシミュレータを同時に起動・接続し,各 ISS が一つのプロセッサをシミュレーションすることで,マルチプロセッサシステムのコシミュレーションを行う.本コシミュレータを用いて,MPEG デコーダのコシミュレーション実験と,ISS の拡張によるオーバヘッドの測定を行った.This paper presents a cosimulator with multiple ISSs where a multiprocessor embedded RTOS can be executed. The ISS was extended from an ISS for single processor embedded systems. In our cosimulator, multiple ISSs and hardware simulators can be executed concurrently with communication. Each of the ISSs simulates one processor. Using the cosimulator, we performed cosimulation of MPEG decoding system, and evaluated the overhead due to extension of the ISS.
