Processing Architecture for Power Efficiency and Performance
Typical Processor Combinations
Arm Cortex-A series processor combinations that meet big.LITTLE requirements are shown below
Arm big.LITTLE processing takes advantage of the variation smart devices require in performance by combining two very different processors together in a single SoC.
The big processor is designed for maximum performance within the mobile power budget.
The smaller processor is designed for optimal efficiency and is capable of addressing all but the most intense periods of work.
big.LITTLE software automatically handles the allocation of tasks 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 to an appropriate core based on the performance required.
Operating system software to run on the big.LITTLE hardware and is fully supported by the broader Arm ecosystem.
