Hmm... one idea that kind of fits - an open hardware 3D graphics engine?
TI has a background of doing fast DSP/RISK CPUs, so they'd have some related expertise.
'Game changing', because it's for gaming, but most importantly _changing_ because the current state of open-ness in 3D engines is an abysmal disaster. There's currently no fully documented 3D hardware engine that I know of - all of them are secret, with only binary-blob software drivers publicly available. And those only for Windows, plus if you're very lucky, a deliberately flakey version for Linux.
The end result is, that if you want to do a 3D graphics engine for some non-Windows platform (that isn't Linux either) you are totally out of luck.
Putting it another way, if someone wanted to challenge the Wintel OS monopoly, with an OS and GUI that was actually a decent 3D environment (as opposed to Microsoft's retarded 'Metro' Win8), they JUST.PLAIN.CAN'T at the moment. Regardless of how much the world needs some way to escape from the Microsoft insanity. (Which doesn't involve the 'million monkeys' different kind of insanity of Linux.)
So.... I WISH that's what TI has up their sleeve. But I doubt it will be.
