EmbedVm is a fully functional virtual machine that runs inside the ATMEL MCU. It can easily be ported to other CPU architectures as it is entirely written in C.
The VM itself takes ~3KB of program memory and consosts of ~300 lines of code.
There are two ways to write programs to run inside the virtual machine.
There are two compilers that target EmbedVM: There is a compiler for a C-like high level language and there is a compiler that can transform python code to VM bytecode. The compiler for the C-like language is part of the EmbedVM sources. The python compiler can be found here.
