MARS (MIPS Assembler and Runtime Simulator)

An IDE for MIPS Assembly Language Programming

MARS is a lightweight interactive development environment (IDE) for programming in MIPS assembly language, intended for educational-level use with Patterson and Hennessy's Computer Organization and Design.

Features:

- GUI with point-and-click control and integrated editor. The three icons shown here denote "run", "single-step", and "single-step backwards

- Integrated editor, featuring multiple file-editing tabs, context-sensitive input, and color-coded assembly syntax. All assembly files in a directory (folder) may be assembled into a single executable.

- Easy set/removal of breakpoints using check boxes

MARS features overview: (List of features by version):

* GUI with point-and-click control and integrated editor
* Easily editable register and memory values, similar to a spreadsheet
* Display values in hexadecimal or decimal
* Command line mode for instructors to test and evaluate many programs easily
* Floating point registers, coprocessor1 and coprocessor2. Standard tool: bit-level view and edit of 32-bit floating point registers (screenshot).
* Variable-speed single-step execution
* "Tool" utility for MIPS control of simulated devices. Standard tool: Cache performance analysis tool (screenshot).
* Single-step backwards
