Sim Alpha Version 1.0: Simple and Readable Alpha Processor Simulator

摘要

We have developed a processor simulator SimAlpha Version 1.0 for research and education activities. Its design policy is to keep the source code readable (enjoyable and easy to read) and simple. SimAlpha is written in C++ and the source code consists of only 2,800 lines. This paper describes the software architecture of SimAlpha by referring to its source code. To show an example of SimAlpha in practical use, we present the ideal instruction-level parallelism of SPEC CINT95 and CINT2000 benchmarks measured with a modified version of SimAlpha.
