ah okay fair enough. I was just curious if he planned to reverse engineer ones with 8gb or more in the later future.
reverse-engineering i have come to the conclusion is a total - and criminal - waste of time and effort. by the time all features are 100% stable it's several YEARS down the line. look at how long ago the A64 was released, and the libdram code STILL HAS NOT BEEN REVERSE-ENGINEERED. it's 200 lines of code for fuck's sake.
NO.

that should give you some idea of how insane pretty much every single fabless semiconductor company really is. they're just not paying attention: every single one of them makes at least one compromise, somewhere, and because it's an *integrated* SoC there's absolutely nothing that can be done about it.
so we need to be of the order of a MILLION units to be in a position to influence these people. and if you're going for a million units, you might as well get your own SoC custom-made.
anyone knows of an open silicon H.264 and MPEG design that is capable of up to 1080p60 video decode, do let me know.
