RISC

/prog/, I'm working on a RISC instruction set that is more RISC than any RISC out there. I've devised an instruction format, plus fifteen core instructions that should suffice for any programming out there. The instruction format, instruction forms, and instructions can be found here:

Any comments or suggestions?

So I write s 0, 0, 255 to write out 2^255 bytes to memory. The processor takes an exception halfway through. How does it resume execution after the exception handler completes?
