Three Simulator Tools For Teaching Computer Architecture:

Teaching computer architecture (at any level) is not an easy task. A critical mass of educators has begun using visualizations of different computer architectures based on simulators to enhance learning. Here we present three representative computer simulators for learning which show: (1) a growing consensus for computer simulation as a teaching tool for complex dynamic processes such as computer architecture and (2) one solution to meet the wide spectrum of target populations and didactic goals for teaching computer organization and architecture. The three simulators we describe are: (1) EasyCPU for the Intel 80X86 family of computer architecture, (2) Little Man Computer for a general von Neumann computer architecture and (3) RTLsim a data-path simulator for a MIPs like CPU. We discuss the additional benefits of computer simulators in terms of flexibility, financial support, obsolesence, accessibility, and research. An appendix is provided for more detailed instructions for each simulator.
