ARM SVE Simulation

This repository contains the minimal setup to simulate programs compiled for ARM w/o SVE instructions.

Steps after cloning the repository

Fetch submodules

git submodule update --init --recursive

Set environment variables

Please edit the variables in scripts/setenv.sh to reflect where your ARM GCC toochain is installed and the cross-compiler prefix.

After that, source the script:

source scripts/setenv.sh

Building GEM5

Please install the dependencies as in GEM5’s building documentation. In particular, it is highly recommend to install:

• libprotobuf-dev
• protobuf-compiler
• libprotoc-dev
• libgoogle-perftools-dev
• libhdf5-dev

After the dependencies are installed, execute:

./scripts/build-gem5.sh

Building M5

With M5Ops we can programatically define the region-of-interest (ROI) and easily dump simulation statistics.

./scripts/build-m5.sh

Testing Gem5 build & M5

Build simple test application:

make -C test

Run test with Gem5:

./scripts/run-binary-in-gem5.sh test/hello-world.x

The simulation statistics should be in m5out/stats.txt.
