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?

probably, though perhaps not?

you only have to check the very first bit to see if its a 16bit instruction >> branch to 16bit decoder //etc. etc.

just using a big select case would be pretty slow// there would be binary-tree style decoders already?
