Duke ECE550 18Fall Lab4

CacheSimulator

Background

This project is for Duke ECE550 18fall, the requirements available at Lab4.pdf and Testing Specification

This project is developed by the following people

• Yifan Men [email protected]
• Yukun Yang [email protected]
• Hongliang Dong [email protected]

It simulates Cache functions and also calculate the rate of hit and miss.

This version only implements LRU policy. RND policy and other policies should be developed further.

Usage

Several parameter should be assigned in simulator.cpp.

The result of simulation:
