iRISC is an ARMv7 assembly language interpreter and computer architecture simulator. The idea behind this application is to expose the state of the hardware after each line of an assembly program is executed. This allows the concepts which prop up the much higher level programs to be more easily visualised. The interface is built to be as interactive as possible, reacting in real time to user input and exposing more detailed information on mouseover. Emphasis is placed on exploration to learn how a computer operates. There is also an accompanying tutorial which is currently work-in-progress. If you think this application is of interest to you, you can access my hosted version here.

This project is based on a similar project I created as part of my masters year of study. That project is a GUI C application, so, as you can imagine, compilation and distribution - kind of a nightmare. However, I was quite impressed with how well my desktop application turned out, so I decided to rewrite the whole thing for the web.

I am not accepting pull requests at this time. I am not well researched on the topic, but, if I can generate some interest, I would like to distribute this software commercially to institutions. I don't want to complicate the issue by introducing questions as to whether or not I own some portion of the code. I am happy to take feature requests, bug reports, etc. Anything that will improve your experience with the app. But until I am more clear on the direction I want to take this software in, I would like to implement these myself.
