Doesn't this run on one of the CPUs Sega used in the Saturn or Dreamcast?

- opencl 5y agoNot quite the same CPU but they're all based on the SuperH ISA. The 32X and Saturn both had dual SH-2s, Dreamcast had an SH-4, and Casio uses SH-3 and SH-4. The Dreamcast SH-4 has an FPU but the Casio one doesn't.
- whizzter 5y agoSame as in the Dreamcast yes, albeit the Casio seems to be clocked far lower (29mhz in Casio vs 200mhz for DC). Also the memory seems a bit anemic at 60ish-kb vs 16mb main for the DC (+8mb videomem and 2mb audiomem). It was a fine CPU for the era with parallel instructions but also a fairly deep pipe compared to other contemporaries so it did best with a bit of hand tuning. (We worked on a DC game and Transform&Lighting loops needed hand optimizations iirc)
- xeeeeeeeeeeenu 5y ago>29mhz in Casio It's extremely overclockable, though: http://pm.matrix.jp/ftune2e.html http://pm.matrix.jp/ftune2e.html
