iPAD is ARM based29 Jan 2010 09:28
The core Apple A4 chip consists of an ARM Cortex-A9 MPCore, the same processor that powers the NVIDIA Tegra and Qualcomm Snapdragon. The graphics unit is a ARM Mali 50-Series. The key thing to note here is that this is all mostly ARM IP.
Broker Panmure has estimated that ARM will get a royalty payment of 60 cents to 80c for each iPad sold and has increased its 2010 forecast by 1% in 2010 and 2% in 2011.
