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 reads compiled code from  or from stdin.

Execution via the #! format is supported.

as-jelvm reads assembler sourcecode from stdin.

Outputs compiled code to stdout.
