Here's a possibly stupid question, but i've never seen anything about this. Are there any architectures that have hardware support for complex arithmetic? For example, dividing two complex numbers (in rectangular form) takes 6 multiplications, 2 divisions, and 3 add/subtracts, if i count correctly. With appropriate functional units that can be hooked up in the right way, this could be done in a couple of clock cycles. Are there machines with complex arithmetic instructions? In a more RISC vein, what instructions are out there that can be used for fast complex arithmetic?
