An Instruction Set Simulator based on DBT-RISE implementing the EveCore Instruction Set.
This project is a showcase of the DBT-RISE Library, implementing a simple Instruction Set. It offers three (partial) implementations and some very basic example programs. Notably two different Simulation approaches are shown, a simple Interpeter based and one using Just-In-Time Compilation.
The EveCore is a Microcontroller Architecture created to be a very simple (but still usefull) Microcontroller. Documentation, a System Verilog Implementation and more can be found here.
This repository consists of two main branches:
- The 'manual' branch consists of a minimial handwritten implementation of the interp and tcc Simulation engine. It only implements some of the EveCore Instructions.
- The "coredsl' branch showcases the approach of using a higher level description of the core to quickly implement new instructions or alter the core. It also provides a more complete instructions set and some more features.
This project uses cmake and conan as build tools. Python can be used for setup.
Step-by-step instructions on how to set up the project:
- Clone the repository:
git clone <repository-url> - Navigate to the project directory:
cd <project-directory> - Use python to create a venv:
python3 -m venv .venv && source .venv/bin/activate - Install conan and cmake:
pip install conan cmake - Build the project using the CMakePresets:
cmake --preset Debug && cmake --build build/Debug -j
When building, two executables are created: eve_sim_interp and eve_sim_tcc. Both of them are a standalone ISS, a executable in hex format can be loaded using the --file option.
For an overview use the --help option.
