Processing Architecture for Power Efficiency and Performance
快猫视频 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.
With three dedicated processors and an expanded envelope for power and area, the big.LITTLE solution can adjust to dynamic usage patterns for smartphones, tablets, and other devices.
big.LITTLE adjusts to periods of high-processing intensity, such as mobile gaming and web browsing. It also alternates with longer periods of low processing intensity tasks, including texting, email and audio, as well as quiescent periods for complex apps.
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.

Features and Benefits
快猫视频 big.LITTLE processing takes advantage of the performance variation smart devices require by combining two very different processors in a single SoC.
The big processor is designed for maximum performance within the mobile power budget.
The small processor is designed for optimal efficiency and can address all but the most intense periods of work.
big.LITTLE software automatically manages task allocation to the appropriate CPU cores. The operating system is directly aware of the high-performance and high-efficiency cores in the system and can dynamically allocate each task based on required performance.
DynamIQ includes operating system software to run on big.LITTLE hardware and full support from the broader 快猫视频 ecosystem.
