The key to ARM Holdings plc's "big-little" dual core scheme is the ability to switch as quickly and seamlessly as possible between processing on the Cortex-A15 MPCore and the new Cortex-A7 core, according to Peter Greenhalgh, an ARM engineer who served as the lead designer on the A7.
"We've designed them so that you can transition really seamlessly and quickly and got the software to do it in a seamless way," Greenhalgh said in an interview last week in San Francisco.
