When Apple debuted the iPad earlier this year, Steve Jobs announced that the A4 CPU was a custom job made specifically for the new tablet device. Upon closer inspection, including some pretty crafty teardowns, it was revealed that it was a custom package-on-package ARM with integrated memory and GPU.
It's now revealed by the New York Times that Apple has purchased the chip firm that many believe to be responsible for some of the A4's design – Intrinsity of Austin, Tex.
While neither Apple nor Intrinsity are commenting on the deal, analysts estimate that the deal was worth around $121 million.
Together with PA Semi, Apple has amassed a considerable amount of CPU talent – no doubt with the intention to focus more heavily on in-house development of technology that its competitors can't have.
