 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

3 videos from cmm2 and pico computer (mmbasic7) 1. both computer are calculating kind of cellular automaton. algorithm in basic, many if and thens per pixel. picomite ist twice as fast. source code is the same. video at youtube: pico is left - cmm2 is right 2. changed demo from matherp for the ray command: resolution 640x480 same source cmm2 not in picomite mode cmm2 is fast and smooth picomite is slower video picomite: ray - picomite video cmm2: ray - cmm2 |

I think this is sort of what I expected. I'm not sure about test 1, but in test 2 the CMM2 has dedicated high speed RAM for the video. The PicoMite has to make do with ordinary RAM which, although on-chip, isn't particularly high speed. I assume that the Pico is a PC3 using HDMI? That may also introduce an overhead over using VGA, I don't know. The two systems are very different in terms of hardware, even if they are both running similar MMBasic. Just for giggles, try the Pico with the compiler on if you can. :) Mick Zilog Inside! nascom.info for Nascom & Gemini |

Please post the cellular automation code so I can use it to test. I suspect the difference is that one of the commands is waiting for frame blanking in the CMM2 and not in the Picomite |
