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:

Yes, I meant something like this. For immediate (and whatever others), 3 bits from the opcode field are combined with the other immediate field to form an 8-bit immediate. For the other instructions, the whole 6 bits is used as the opcode.
