Apple Uses Own Chip In iPad, The 1GHz Apple A4

| iPad

Apple is using the first chip to come out of its PA Semi acquisition in its new iPad, a processor called the Apple A4. Apple CEO Steve Jobs made the announcement at the media event Wednesday where the iPad was unveiled, according to Engadget's coverage of the event, where he said, "It's powered by our own silicon. The 1GHz Apple A4 chip. It screams."

The iPad is Apple's new tablet, a device focused on e-mail, browsing, watching videos, listening to music, playing games, and reading ebooks. While we haven't yet handled the device, commentary from Apple's media event backed up Mr. Jobs's claim that "It screams," with people saying that the device is responsive and didn't stutter when playing HD video.

Apple bought PA Semi in April of 2008, and it has long been speculated the company planned to use chips designed by the firm in its mobile devices. The 1GHz model being used in the iPad is the first such chip to make it into a shipping Apple product.

Yaaaawwwwnnn.

I thought this device would be useful to interface to database but I doubt Oracle will support this architecture.  :-(

Anyone know what the instruction set architecture for the Apple A4 is? Considering the iPhone 3GS used the Cortex-A8 I’m almost convinced the A4 is a modified A8 (meaning that it uses the ARM architecture).

Right.  Because there are no web API’s for database access… and no SDK to build custom apps on this platform… and database == Oracle in every context.

Move along, nothing to see here.

PA Semi’s specialty was ARM processors before Apple bought them, as I recall.  I imagine it’s a safe bet that the A4 is also ARM.

Good to know. That (potentially) answers a question I had: How do iPhone apps perform on this sucker? I wondered if emulation was necessary; this strongly points to “no.”

PA Semi has its roots in Digital Equipment Corporation, that made the Alpha and the StrongARM processors.  ARM has been a staple of their work, so I’m fairly confident that’s the basis of the architecture they’ve used.

@Mike:  Please refer to the info provided by Apple re the iPad.  the SDK is available today, to build apps for the iPad.

Remember folks…  this is iPad 1.0.  Apple sells a bunch to early adopters and then brings out iPad 2.0

Familiar scenario?

@WetcoastBob
I know what you mean , but…  Nah, this iPhone/iPod 3.2.  It’s the evolution of established products.
