Propeller is awesome. Propeller II will be more awesome. What's next?
What about a DSP? I don't think it would take much addition on top of Prop II. What would we need?
* 32*32+64->96 MAC (Multiply/accumulate) instruction (Really only need 72, but 96 is easier)
* A pair of 96-bit registers made up of three sequential 32-bit registers, each.
* Barrel-shifter that can be used on Add and Move operations. 16-bit range would probably be sufficient.
I'm making these claims based on my time playing with a Freescale 56371 and seeing how fast it is able to do some operations with just a few extra ops. Add in the fact that Microchip is pretty successful with the DSPic and this starts to look like a pretty good idea.
