摘要

通用微处理器是现代信息产业中的核心技术之一

它可以广泛应用到国民经济的方方面面.本文针对超深亚微米通用微处理器中的多级TLB设计开展研究.通过踪迹驱动仿真

对不同的TLB架构进行了大量的分析比较

在分析了失效率、尺寸和设计复杂度等因素后

进一步参考北大众志863系统芯片的实际运行技术参数

引入到仿真结果中进行了实际性能分析和计算

得出了指导性的结论.对于性能相近的同类微处理器设计也具有较好的借鉴意义.

Abstract

Microprocessor is one of the key technologies of IT industry.This research focuses on multi-level set-associative TLB performance of the general purpose microprocessor.We analyze the performance of different TLB structures using trace-driven simulation

and discuss chip size and design complexity.Above experimental results are applied to Unity-863 environment to get valuable conclusions.It's also applicable for similar processors and system-on-chip.
