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.

Just because a binary doesn't include a specific arch doesn't mean it's not a UB (yes I know that sounds weird but keep reading) .

Apple *DO* create ARM code 'universal binaries' - UB's are merely a container for various different architecture code - It's what the Magic Bit is for at the start of ALL binaries compiled by Xcode).

Also every single iphone application can be compiled to run on the iPhone simulator. The key thing to know is that the iphone simulator is exactly what it says it is - it is a simulator which runs x86 code not ARM - it is NOT an emulator.

It's also highly likely there is a full OSX Snow Leopard build running on Arm deep in the bowels of Apple just as there were builds on 10.0 running on x86 for years before his Jobsness admitted it during a keynote.
