VArchC

ArchC-based Approximate Computing Framework

VArchC is a framework built to test, validate and evaluate Approximate Computing techniques.

ArchC is a powerful and modern open-source architecture description language designed at University of Campinas by the ArchC team in the Computer Systems Laboratory, Institute of Computing.

  • ArchC utility library, i.e. all files stored in the src/aclib directory of the ArchC source tree, are provided under the GNU LGPL license. See the Copying Lib file for details on this license.

Dependencies

  1. GNU autotools:
  • m4
  • autoconf
  • automake
  • libtool
  1. Build tools:
  • GCC
  • GNU Make

  1. GNU Bison

  2. GNU Flex

Build and Install

  1. Create a directory to store VArchC and access it

  2. Build and install SystemC

wget http://www.accellera.org/images/downloads/standards/systemc/systemc-2.3.1.tgz
tar -xvf systemc-2.3.1.tgz
cd systemc-2.3.1
./configure --prefix=$(pwd)/../SystemC/
make
make install
cd ../
  1. Build and install ArchC
git clone https://github.com/VArchC/ArchC.git ArchC-SRC
cd ArchC-SRC
./autogen.sh
./configure --prefix=$(pwd)/../ArchC --with-systemc=$(pwd)/../SystemC/
make
make install
  1. Setup environment
source env.sh

We recommend to add this line to your ~/.bashrc to set the ArchC environment automatically.

echo "source env.sh" >> ~/.bashrc
source ~/.bashrc
  1. ArchC installation is ready. You need a Processor Model to get started.

Processor Models

VArchC needs vanilla-ArchC to be slightly modified for compatibility. Currently the following models are available:
