Usage

Ripes may be used to explore concepts such as:

• How machine code is executed on a variety of microarchitectures (RV32IMC/RV64IMC based)
• How different cache designs influence performance
• How C and assembly code is compiled and assembled to executable machine code
• How a processor interacts with memory-mapped I/O

If this is your first time using Ripes, please refer to the introduction/tutorial.
For further information, please refer to the Ripes documentation.

Downloading & Installation

Prebuilt binaries are available for Linux, Windows & Mac through the Releases page.

Linux

Releases for Linux are distributed in the AppImage format. To run an AppImage:

• Run chmod a+x on the AppImage file
• Run the file! The AppImage for Linux should be compatible with most Linux distributions.

Windows

For Windows, the C++ runtime library must be available (if not, a msvcp140.dll error will be produced). You most likely already have this installed, but if this is not the case, you download it here.

Building

Initially, the following dependencies must be made available:

• A recent (>=6.5.0) version of Qt + Qt Charts (not bundled with Qt by default, but can be selected during Qt installation)
• CMake
• sudo apt-get install libegl1-mesa-dev

Then, Ripes can be checked out and built as a standard CMake project:

git clone --recursive https://github.com/mortbopet/Ripes.git
cd Ripes/
cmake .
Unix:               Windows:
make                jom.exe / nmake.exe / ...

Note, that you must have Qt available in your CMAKE_PREFIX_PATH. For further information on building Qt projects with CMake, refer to Qt: Build with CMake.
