ARM today announced the Cortex A7 MPCore application processor for low-cost smartphones and tablets. This new application processor architecture is one-fifth the size of previous generation A8 chips and is five times as power efficient. ARM also announced a new processing system that it calls big.LITTLE. Systems on a Chip that use big.LITTLE processing will have two processors, a more powerful Cortex A15 and the smaller A7. It can then dynamically choose between the two processors in order to best match the processing and power management needs at any given moment. ARM says the new A7 uses 28nm fabrication to create a footprint that is smaller than half a squared millimeter. ARM believes that the A7 will deliver the same computing power to $100 smartphones in 2013/2014 that today's $500 smartphones offer.
