I wrote a bytecode compiler for my NPCI language. You can find a
description here:

As you can see it's been about 6 years since I worked on it.

I think such a compiler already exists. Give me a virtual second...

Here it is: http://pyastra.sourceforge.net

It's written in Python. Maybe you can use it as a starting point.

[some snippage]

The language I'd like to immerse myself into this summer is Forth. NPCI
runs on a stack based virtual machine and Forth simplifies parsing to
nothing by using a couple of stacks and RPN for parsing. Just from noodling
around in the last year, I think a productive system can be forumlated with
a really small onchip core.

Personally I'd like to get back to a system where all development occurs
onchip.

Just some thoughts.
