JIT-ISS
A versatile Just-in-time (JIT) compiling instruction set simulator (ISS)
JIT-ISS README
This is currently a proof of concept and work in progress, so use at your own risk. It is currently set-up as an Eclipse CDT project and based on LLVM. To build it you need latest LLVM and Eclipse CDT version 4.6 aka Neon.
To build with SystemC the define WITH_SYSTEMC needs to be set. Then a simple proof-of-concept system is created. Mainly missing are platform peripherals and interrupt handling. It reaches about 5 MIPS in lock-step mode on a MacBook Pro (Core i7-4870HQ@2.5GHz) running in a Docker container.
JIT-ISS uses libGIS (https://github.com/vsergeev/libGIS) as well as ELFIO (http://elfio.sourceforge.net/), both under MIT license
What's missing
- only AVR instruction set implemented but not verified
Planned features
- add platform peripherals
- timers
- gpio
- ext interrupt registers and functionality
- and more
Quick start
- you need to have a decent compiler, make and cmake installed
- install LLVM 3.9 or 4.0 according to http://apt.llvm.org/
- download and install SystemC from http://accellera.org/downloads/standards/systemc
- optionally download and install SystemC Verification Library (SCV) from Accelera into the same location
- checkout source from git
- start an out-of-source build like so (e.g. when using LLVM 3.9 and bash)
cd JIT-ISS
mkdir build
cd build
LLVM_HOME=/usr/lib/llvm-3.9 cmake ..
make
- if the SystemC installation is not to be found be cmake you can optionally specify the location by either setting the following environment variables pointing to the installation
- SYSTEMC_HOME
- SYSTEMC_PREFIX
