The Telegraph: Mobile processor maker ARM has announced a new chip that uses very little power, greatly extending battery life. Called the A7, the new chip will also be very inexpensive, allowing smartphone makers to offer devices that cost less than $100 for capabilities that rival today's top-of-the-line phones. ARM calls this new technology "big.LITTLE" processing.
The new chips could also be used alongside A15 chips in higher-end phones dubbed "superphones." These devices could tap the high-performance A15 chips for demanding tasks like HD video and gaming, and then switch back to the A7 chips for more mundane tasks to extend battery life.
