JArmEmu

JArmEmu is a software simulator written in Java that models the ARMv7 architecture for educational environments. It allows instructors and students to observe how instructions execute at the processor level without requiring physical ARM hardware. The program provides a controlled setting to run simple machine code programs, making it suitable for computer science courses focusing on low-level system design and instruction set architecture.

Because it is implemented in Java, the application runs across different operating systems equipped with a Java Runtime Environment, though its primary platform specification targets Linux. Users can load programs into the simulated memory space and inspect registers as instructions are processed sequentially. The simulator serves as an instructional aid rather than a complete system emulator, omitting peripheral device modeling to concentrate strictly on core CPU behavior and instruction execution pathways.
