JArmEmu is a simple, user-friendly simulator that provides basic control and information about a simulated ARMv7 architecture.

JArmEmu is powered by an ARMv7 interpreter built Ex Nihilo for this project, which provides real-time syntax highlighting, intelligent auto-completion, memory, stack and register monitoring...

You can write your program using the ARMv7 instruction set (refer to Instructions.md in the GitHub repository) and include GNU Assembly directives (only the basic ones are implemented, you can refer to syntax highlighting or auto-completion to see if it is available).

This project was created by Kévin "FoxYinx" TOLLEMER and Alexandre "Deleranax" LECONTE, students at INSA Rennes (independent project). It is distributed in open source under GPL3 (refer to the LICENCE file).
