Unlike Intel’s Atom chip, the ARM Cortex A9 sips power at about 300 milliwatts or less, while the Atom uses up to 2 watts. This reduction in chip size decreases power consumption while enabling the chip to speed up. Additionally, it is built on a 45-nanometer processes compared to the 65-nanometer process of the A8. Key to the Cortex A9 architecture is that like the Cortex A8 (which the iPhone processor is currently based around) the A9 is multicore. The ARM Cortex A9 can be up to a Quadcore multicore chip, as seen in this diagram. This chip was first discussed by ARM back in mid year 2009.

Engadget is claiming the A4 design is not just ARM architecture based, as we mentioned above, but based on the very latest Cortex A9 series multicore architecture.
Some of the details we now appear to know are flowing in across various sources on the Net. We assume it is ARM architecture-based, but that’s not taking us all the way to where we really want to go. That Apple will keep very close to their chest. We’ll have to dig around to find out who manufactured it and that will likely be easier to obtain than the internal architecture of the chip. It’s high-performance, lower-power system-on-a-chip custom silicon.

The A4 is likely based on a customization of an ARM processor design as Apple holds a special class license to ARM architectures which enables them to modify architectures. 1 Ghz chip may integrate graphics in a system-on-a-chip package. That is why the US Government got hold of some of their first processors for military equipment–because they were that good.Īpple's PS Semi produced A4 processor in the new iPad. This group has world-class expertise in high-performance/high-energy efficient chip design. This is a PA Semi team produced chip, make no bones about it. The details that matter to us at Architosh are centered around this device’s raw power to handle large document images both in viewing capability and creation.Īpple is calling the new internally designed main processor (CPU) the A4. I have much to do today I’m going to make this blog post pretty short.
I’ve been reloading for minutes now every 15 seconds. The Apple iPad webpage just went live about 60 seconds ago.
I have to admit it actually is better sounding than iSlate and iTablet…neither of which I cared much for. So contrary to my earlier statement that he would distance the new device from the word “pad” Jobs’s new toy is in fact called the iPad. Not! Clearly Jobs is a fully mature human being now, having gotten completely past Scully and the Newton MessagePad. I was hoping they would surprise us with something new and clever.
