Tom's accent is pretty thick to this old Iowa farm kid, and his audio a/d is being overdriven and is clipping the audio pretty bad, so I'm missing some details while watching the video, but I rather like the basic outline as it would also appear to make a realtime kernel much less important (or I don't fully understand due to the accent). In any event, it seems like its worth investigating. Particularly in view of the fact that 8 core arm64's are already shipping. Twould be most encouraging if a 40 to 50 MHz spi interface has been developed to interface to the likes of a mesa 7i90. Or a fast parport has been done on the gpio available on these credit card sized things. No negative vibes from here IOW. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
