A Study of Acceleration Technique for Many-core Architecture Simulation Considering Global Program Structure

本文提出了一种快速、高精度的多核和多核处理器体系结构仿真技术。通过该技术，体系结构模拟器可以根据并行化应用程序在多核或多核上执行的假设，适当地改变其精度和仿真速度。对4种不同特性应用程序的评价结果表明，16核多核仿真在0.52%误差范围内最大加速提升443次，在2.75%误差范围内平均加速提升218次。

A fast and high accuracy architecture simulation technique for multi-core and many-core processors are proposed in this study. By this proposed technique, an architecture simulator changes its precision and simulation speed appropriately under the assumption that a parallelized application is executed on a multi-core or a many-core.The evaluation results with four applications each of which has different characteristics show the 16-core multicore simulation gives 443 times speedup within 0.52% error in maximum, and 218 times speedup within 2.75% error on average.
