| 摘 要： | 针对异构处理器平台进行X86体系结构仿真的问题，提出一种I/O框架，介绍该框架中的3个主要模块：总线与接口函数的注册与映射，桥芯片中数据结构的设计与函数体的布局，中断信号选择与传递的实现技术。根据不同框架结构，通过运行SPEC2000测试集，证明该I/O框架与其他同类框架相比，性能可提升10%~20%。

| Abstract: | X86 simulation on heterogeneous processor platform suffer from low performance and other problems. To address these problems, a high performance I/O architecture is presented. This paper describes the design and implementations on bus and interface function, bridge chipset and interrupt system in details. SPEC2000 benchmark test result shows that this I/O architecture＇s performance is higher than the software simulation technology. The performance is promoted by 10%-20%. |
