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.
Feb. 2013: “MARS has been tested in the Softpedia labs using several industry-leading security solutions and found to be completely clean of adware/spyware components. . Softpedia guarantees that MARS 4.3 is 100% FREE, which means it does not contain any form of malware, including spyware, viruses, trojans and backdoors.”
Download MARS from Softpedia (version on Softpedia may lag behind the version on this page).
New for 4.0: new editor, featuring multiple files, context-sensitive input, and color-coding.
