Neksus

Neksus is a full system simulation framework for System-in-Package (SiP) and System-on-Chip (SoC) applications. We integrate the IP definations given by GemDroid (https://github.com/gemdroid/GemDroid), DRAMSIM2 as memory module, and popular network simulator Booksim for a close loop simulation. It is based out of gem5 framework. Booksim has been configured for an optimized SiP interconnect. It supports common audio-video mobile applications like Youtube, Skype, etc. Application traces are collected from android emulator (https://github.com/huz123/GemDroid_QEMU).

Follow the below instructions to build and run Neksus.

Build

    git clone https://github.com/gemdroid/GemDroid.git
    cd GemDroid/
    hg clone http://repo.gem5.org/gem5
    cd gem5/
    hg update -r 10231
    rm -rf src/
    cp -r ../gemdroid.src ./src
    cp -r ../gemdroid.needed/gemdroid.dramsim2/* ./ext/dramsim2/
    mkdir traces
    cp your_trace.trace tarces/
    cp ../gemdroid.needed/*.txt ./
    scons build/ARM/gem5.debug or scons build/ARM/gem5.opt
