摘要

本文提出了一种全新的获得访存trace的方式

并设计实现了基于硬件的零开销多平台实时访存Trace工具——MTT(Memory Trace Tool).详细介绍了MTT在采样配置、地址识别、trace输出等方面的设计细节

以及接收端配合MTT高效接收分析trace的流程

实现了一个通过MTT获得程序访存trace的完整方案.相比已有方法

MTT具有许多特点:(1)对程序透明;(2)零开销

无内存污染问题;(3)实时获取完整的全系统访存Trace;(4)可实时配置的多种在线Trace分析手段;(5)具有操作系统平台无关性.

Abstract

We propose a new approach to track memory reference trace and present a hardware-based Memory Trace Tool(MTT)for real systems.This paper details the design of MTT

including sampling configure

translating address

outputting trace and analysis of memory trace

which implement a complete solution to acquire and analyze memory reference trace.Compared to existing methods

MTT has several features:(1)be transparent to applications and system software;(2)be nearly zero-overhead and no memory pollutions;(3)be available to obtain full-system trace on real systems;(4)provide various online analysis approaches;and(5)be independent of system platform

support different CPU and OS platform.
