【摘要】：随着计算机系统规模的不断增长,计算机系统结构的研究对于如何更有效地利用各个部件的性能显得尤为重要.但是在系统结构的研究中,由于研究对象规模过大,采用模拟器进行模拟测试是一种常用的方法.但是在使用全系统模拟器的时候,将整个系统进行模拟会造成实验效率的降低和模拟器程序的维护困难.因此,使用基于trace输入的模拟器成为了一种提高模拟器效率的常用方法,但是由于trace不能良好地表现计算机系统某些部分的运行特性,难以避免地存在一定的模拟误差.对此,提出了一种基于trace精度改进的内存系统模拟器优化方法,通过增加trace中包含的内容、提高trace的精度并在内存系统模拟器中实现相应的支持机制,从而在不影响模拟器运行效率的情况下提高内存系统模拟器的运行精度.
[Abstract]:With the increasing of computer system scale, the research of computer system structure is very important for how to make more effective use of the performance of each component.However, in the research of the system structure, because the research object is too large, it is a common method to use simulator for simulation test.However, when using the whole system simulator, the simulation of the whole system will result in the reduction of the experimental efficiency and the difficulty in maintaining the simulator program.Therefore, the use of simulator based on trace input has become a common method to improve the efficiency of the simulator. However, because trace can not well represent the running characteristics of some parts of the computer system, it is difficult to avoid certain simulation errors.In this paper, an optimization method of memory system simulator based on trace precision improvement is proposed. By adding the contents contained in trace, the precision of trace is improved and the corresponding supporting mechanism is realized in the memory system simulator.Therefore, the running accuracy of the memory system simulator is improved without affecting the efficiency of the simulator.
