Hardware, Embedded Systems And yet another item on the iPad? Are we serious? Yes, we are, since this one is about something that even geeks who aren't interested in the iPad itself should find intriguing. Steve Jobs said yesterday that the iPad is powered by an Apple A4 processor, but contrary to what many seem to think - it wasn't designed in-house at all.

This is a direct quote from Steve Jobs from the keynote:

"iPad is powered by our own custom silicon. We have an incredible group that does custom silicon at Apple," company co-founder Steve Jobs said during Wednesday's keynote. "We have a chip called A4, which is our most advanced chip we've ever done that powers the iPad. It's got the processor, the graphics, the I/O, the memory controller -- everything in this one chip, and it screams."

He did NOT state they designed a completely custom CPU: he very clearly stated what it was, and yes, it is standard practice from the lowest level (digital logic gates as well as analog circuitry) to the highest level to use pre-existing bits of known-good circuit design, just as it is standard practice (except for too many that end up with their code on thedailywtf.com ) in software to reuse existing known parts, and there's still true design going on, it's not like Apple took a pre-existing single chip and relabeled it, as you'd seem to think by your thread's title. Does Apple design every chip they use? Of course not, and they never claimed that! Does Apple use custom silicon that they design how it all works together? They've been doing this since before you were born!
