Mine will most likely have a binary processor, like, say, an arduino, that has at least 6 PWM outputs. It will then simply feed them, giving each function enough time to finish. The arduino is loaded with the program from the PC, and is basically an advanced HDD :P

Perhaps a 4 bit * 4 bit = 8 bit could be added. I have a diagram laying around somewhere so I will post that soon. At the first bit multiply is very simple, but doubles in size with every bit. I think overall that instruction is about 300 transistors if that in not too many

btw: I wonder how many transistors the 256 bit fpu square root instructions take on the sse5 set.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)
