Apple admits to eating ‘iPad chip designer’ • The Register

Last week Apple’s secret purchase of th ARM chip designer, Intrinisity came out. All indications are A4 is a pre-existing project titled Hummingird which was a Samsung/Intrinsity project to create a cell phone CPU. If A4 is the Hummingbird or very much like it, little wonder then that it is so efficient with the battery, does this mean A4 could show up in an Apple iPhone?

What’s the point of licensing computer chip designs from another company if it costs about the 1/3 the price of building it yourself? That seems like a rhetorical question, but I always assumed that people who licensed technology from ARM holdings were aiming to save tons of money compared to fabricating the chips themselves. So how does the Apple iPad A4 cpu figure into this? Well it’s a custom CPU, but according to NYTimes creating a new cpu is serious business.
