MofySim: Mobile Full-System Simulation Framework


Introduction

MofySim consists of a simulated mobile system, a simulated server system, a simulated Ethernet, an architectural statistics file, a system configuration file, and converters for analyzing the energy consumption. MofySim includes an enhanced gem5 simulator with source codes, Android and Linux Kernel images for a mobile system, embedded ARM Linux and Kernel images for a server system, energy converter tools, and McPAT configuration files. MofySim provides the configuration of network conditions and power models for CPU/caches, DRAM, network interfaces, and display.

The below paper shows the detailed information and examples.
