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. Have you even attempted to implement any nontrivial algorithm in it? Have you simulated it? Implementing a synthesizable Verilog/VHDL simulation would be educational for you.
