Stack based virtual machine interpreter and a C compiler.
This development effort is intended to support an undergradutate Operating Systems class. It has been used in both the Operating Systems and Compilers classes at Oregon Institute of Technology for several years.
For the Compilers class, students develop a compiler that outputs stackl assembly code. This allows students to perform code generation without the need to learn a complex assembly language.
For the Operating Systems class, students are able to write interrupt service routines, system calls, process schedulers, etc. Since the interpreter supports both user and priviliged modes, students get the experience of writing kernel code without the need for dedicated hardware (or a dedicated VM).
