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?

Fucking Terrible!

You can't even copy the value of one register into another. Instead, you have to write the first register out to memory one byte at a time, read the data back into the register one byte at a time and then read the data into the target register one byte at a time.

Also, no way of detecting overflow/underflow in arithmetic operations, or perform bit rotation etc. etc.

Except Thumb was designed by people who had a fucking clue.
