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t、race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.
We propose a new approach to track memory reference trace and present a hardware-based Memory Trace Tool （MTY） 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 pollutions; （3）be available to obtain fuU-system trace on real systems; （4）provide various online analysis approaches; and （5） be independent of system platform, support different CPU and OS platform.
