摘　　要：本文设计了一款系统结构参数可配置的多核全系统模拟器MPSimu(MPSoC Simulator),采用混合精度建模技术实现模拟器速度与精度的平衡,集成了调试器和布局优化器用于工作数据收集、调试及布局优化.实验结果表明,MPSimu较为准确地模拟了目标系统的行为,测试程序在MPSimu上运行的周期与系统实测周期误差在10%以内,为MPSoC的性能评测和架构分析提供一种高效的解决方案.This paper designs a multi-core system simulator MPSimu（MPSoC Simulator） with configurable system structure parameters, which realizes the balance of speed and precision of the simulator by using the hybrid precision modeling technology, and integrates the debugger and the layout optimizer for work data collection, debugging and layout optimization. The experimental results show MPSimu simulates the behavior of the target system more accurately. The test program running on MPSimu has a period error of less than 10% with the measured period of the system, providing an efficient solution for MPSoC performance evaluation and architecture analysis.
