Suggestions : Release a linux version ;)

Improvement : It's possible to change the microblaze source to add an offseting capability to fetch/store So image sF is your stack pointer, you can save regs on the stack:

sub sF, 4 store s0, 0(sF) store s1, 1(sF) store s2, 2(sF) store s3, 3(sF)

That should allow for some codesize reduction I think.

Also, theses modification to the microblaze don't require more resources. (just some LUT3 changed in LUT4).

The examples seem a bit like a macro based C compiler. The code for reading/writing I/O is huge. Maybe it is better to introduce some language extensions that will map variables into the I/O space. Most

8051 C compilers do this.
