    Code Red Sim

    Code Red Sim

    A low-power ISA design and simulator for a 2010 IEEE competition

    This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

    Code Bubbles is a front end to Eclipse designed to simplify programming by making it easy for the programmer to define and use working sets. It provides compact function-based views of the code (all backed by the underlying files) that are displayed in bubbles and that are easily moved around and manipulated on the screen. The bubbles are fully editable. A large bubble area lets the programmer set up different working sets simultaneously and easily move between them.
