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?

could use something like this if you ran out of op-codes

i think most of the instructions so far would fit in just five bits of opcode, bar that 'i, so what op/? could do is use the very first bit as a 16-bit / 24-bit length instruction signal?

...full new 23 bit space to use//larger address spaces + more opcodes?
