The Super FX co-processor was built into games cartridges such as Star Fox, Yoshi's Island and Doom. It was used for sprite transformations in Yoshi's Island and 3D effects in Star Fox and Doom, as well as for rendering polygons.
This was a RISC (Reduced Instruction Set Computing) processor used in addition to the SNES CPU, which implies that the chip was specialised for certain tasks. As there were fewer instructions, the chip could more easily be optimised for these instructions. What specific tasks was the Super FX designed and used for?
