jelvm is a small virtual machine interpreter.

The aim is to have a small vm that can be targeted by high level language compilers. Performance is not the first priority. Simplicity is important. It is possible to call C functions from the vm code. There is a system call interface for performing kernel system calls. An assembler is included: see "jelvm_instruction_set.txt" and the as-jelvm program.

You can easily include the vm in any C program and execute jelvm code via a simple function call.

Project status: In progress. The 'helloworld.s' program compiles and runs correctly. Bugs need to be found and corrected. More documentation to write. Larger example program needed.

jelvm [-h] [-v] [-D] [program] -h display this help -v verbose -D debugging information concerning the virtual machine

jelvm reads compiled code from or from stdin. Execution via the #! format is supported.

as-jelvm [-h] [-v] [-D] -h display this help -v verbose -D debugging information concerning the assembler

as-jelvm reads assembler sourcecode from stdin. Outputs compiled code to stdout. Ex: as-jelvm < source.s > prg
