ARM's big.LITTLE Processing allows devices to switch between A7 and A15 depending on the workload
UK-based chip manufacturer ARM has announced its most energy efficient CPU for portable electronics, called the Cortex A7, which will succeed the Cortex A8 CPU. The new arrival is designed to work as a stand-alone CPU in entry-level devices, and requires twenty percent the energy of its predecessor while offering twice the performance. High-end smartphones and tablets will also utilize the A7 as an additional source of computing power for less demanding tasks, with main processing provided by the upcoming ARM Cortex A15. Such a combination is dubbed big.LITTLE Processing.
