Super FX

The Super FX is a coprocessor chip used in select Super Nintendo Entertainment System (SNES) video game cartridges. This custom-made RISC processor was typically programmed to act like a graphics accelerator chip that would draw polygons to a frame buffer in the RAM that sat adjacent to it. For those games, the data in this frame buffer were periodically transferred to the main video memory inside of the console using DMA in order to show up on the television display.
