iPhone: "Three Arms Inside"

The CEO of ARM Holdings plc reported that the iPhone was powered not by one but three ARM-type CPU, and even gave the model: the PXA320. This CPU is manufactured by Marvell and feature 256KB cache L2, a 32-bits memory bus and is clocked at 800MHz, but a 1.2GHz model has been rumored too. For sure there is more than enough power to encode video.
We can now understand why Apple did not communicate further in details about the iPhone hardware. First, power consumption needs to be tightly controlled in order to save battery life. One also understand why there is also no details concerning OSX Leopard Mobile, as it requires a multi-CPU management as well as an advanced power management built in the OS. Of course giving a call will only require a small % of this available CPU raw power, and one can expect that Apple did NOT unveiled all the features of this mobile phone.
For sure we will know more when the iPhone will be launched at the WWDC 2007 in June.
