SparcSim is yet another Sparc CPU emulator program (yascep), targeted for education. It is written in Java (1.4.2).

SparcSim is a simplified implementation of a 32-bit Sparc CPU. It does not have things like floating point, traps, processor modes. It has sufficient features to write and debug simple assembler programs so a student can learn basic Sparc assembler language. Having been written in Java, you can tell it's not built for speed. It has a GUI, and the display of the contents of registers and memory is updated in real-time as the program runs.

The ZIP file contains all the source, documentation, the class files (object code), a JBuilderX project file and some screenshots.
