iPad - all the hall marks of hummingbird

Apple today announced the iPad - their slick looking tablet computer. It is based around an ARM architecture processor, but in a chip package designed by their semiconductor team from P.A. Semi. Their role has undoubtedly been vast in the creation of the chip (called the Apple A4 chip), taking on various technologies and combining them together into one SoC.

Their semiconductor manufacturing partner is Samsung, and a recent announcement from Samsung regarding a custom implementation of the Cortex-A8 processor using Intrinsity's Fast14 domino logic seems the prime target for the processor in the iPad.

With Apple's investment in Imagination Technologies, Apple will have one of the latest PowerVR SGX cores sitting nicely alongside the Cortex-A8. This pairing - alongside possible video engines, and other features like high performance memory controllers etc., make the SoC design undertaken by Apple thoughtful, but not mind-blowing. Their use of a domino logic implementation  for the A8 macrocell is the key to the speed uplift, and the low power usage even at just 1V. But there is no mystical P.A. Semi designed custom ARM CPU implementation in there right now. They've merely added the necessary tweaks to get what they already use in the iPhone running as fast as it can possibly go without burning a hole in your purse.

Where Apple seem to be best at differentiating themselves is in the software, though. That thing looks slick, and I can't wait to get a play around with it! The browser and maps look flawless, indicating a very good level of performance in the adapted iphone OS. And their graphics drivers will have to be a step up from what is required for iPhone, given the extra clarity in the display.

I didn't like the name, and I didn't originally like the concept, but Apple stuff is always so beautiful, and it always just works. I now look forward to its arrival here in the UK.

The fact that it doesn't have Intel anywhere near the thing also makes me glad.

  1. The link first in the article I wrote above is now broken, since it points to Intrinsity's website, which is no longer available amid speculation that Apple has bought Intrinsity. As such, you cannot read about the work done by Intrinsity for Samsung.

    A new link is here, which points to Samsung's initial press release:
