Overview
Processing Architecture for Power Efficiency and Performance
Arm big.LITTLE technology is a heterogeneous processing architecture that uses up to three types of processors. LITTLE processors are designed for maximum power efficiency, while big processors are designed to provide efficient, sustained compute performance.
Arm Ultra Processors with big.LITTLE for Peak Performance
Users expect increasingly higher performance from their smartphones and tablets, but battery capacity and power efficiency advances from semiconductor processes are not keeping pace. At the same time, users are demanding longer battery life within roughly the same form factor. This conflicting set of demands requires innovations in mobile SoC design beyond those that process technology and traditional power management techniques can deliver.
Arm DynamIQ
Combines a variety of CPUs into a single, fully integrated cluster, bringing advanced power management and performance for every edge device.
