Lennart Augustsson's obfuscated tiny C byte-code compiler/interpreter
may be just what you are looking for. The unobfuscated version of the
compiler is nicely written and easy to follow. It supports integers,
chars, arrays, pointers, functions with parameters, and most control
statements. As a bonus, it can compile itself. The unobfuscated
compiler is about 600 lines of code.

The VM bytecode interpreter is about 150 lines of code.




The Unobfuscated version of the compiler/interpreter is available
here:

The grammar used and a some usage notes are available here:
