RARS The Ultimate RISC-V Assembler and Runtime Simulator

RARS, which stands for RISC-V Assembler and Runtime Simulator, is a tool that enables users to assemble and simulate RISC-V assembly language programs. RISC-V is an open-source instruction set architecture (ISA) that has been gaining popularity in recent years due to its simplicity and flexibility. However, learning how to write RISC-V assembly language programs can be challenging for beginners, which is where RARS comes in.

One of the key features of RARS is its support for the RISC-V IMFDN Base, which includes both riscv32 and riscv64 architectures. This means that users can write assembly language programs for a variety of RISC-V processors, making RARS a versatile tool for anyone interested in learning RISC-V.

In addition to its support for the RISC-V ISA, RARS also includes several system calls that match the behavior of other popular RISC-V development environments such as MARS or SPIKE. Debugging is an important part of any development environment, and RARS includes support for both breakpoints and ebreak instructions. This enables users to pause the execution of their program at a specific point and examine the state of the CPU and memory.

One of the unique features of RARS is its side-by-side comparison of pseudo-instructions to machine code with intermediate steps. This enables users to see how their high-level code is translated into machine code at each step of the assembly process.

Finally, RARS includes support for multifile assembly using either files open or a directory. This enables users to split their code into multiple files for organization purposes, making it easier to manage larger projects.

How to Install RARS on Ubuntu Linux

RARS can be easily installed through a flatpak package file, which is available for download from the remote flathub store. If you do not already have flatpak and flathub installed on your system, you will need to install them first. Once installed, simply restart your system and proceed with the installation of RARS.

Install flatpak and flathub

Open the terminal application (ctrl+alt+t) and run below RARS flatpak install command.

flatpak install flathub io.github.TheThirdOne.rars

And the installation you can open it from below command.

flatpak run io.github.TheThirdOne.rars

And uninstall RARS using this command.

That’s it.
