BigLITTLE is a heterogeneous multiprocessing (HMP) architecture developed by ARM Holdings. It is designed to improve energy efficiency in mobile devices by dynamically allocating tasks between high-performance "big" cores and low-power "LITTLE" cores. The big cores are typically high-performance, out-of-order execution cores optimized for performance-intensive tasks, while the LITTLE cores are simpler, in-order execution cores optimized for power efficiency.

The BigLITTLE architecture allows the system to switch between different core configurations based on the workload and power requirements. For example, during high-demand tasks, the system can allocate more big cores to handle the workload, while during low-demand tasks, it can switch to LITTLE cores to save power. This dynamic allocation helps to balance performance and power consumption, making it an ideal choice for mobile devices where battery life is a critical factor.

The BigLITTLE architecture has been widely adopted in ARM-based mobile devices, including smartphones, tablets, and wearables. It has also been used in other devices such as routers and servers, where energy efficiency is a key consideration. The architecture is designed to be scalable, allowing for the addition of more cores as needed to meet the demands of future workloads.

In summary, BigLITTLE is a heterogeneous multiprocessing architecture developed by ARM Holdings that improves energy efficiency in mobile devices by dynamically allocating tasks between high-performance big cores and low-power LITTLE cores. It has been widely adopted in ARM-based mobile devices and other devices where energy efficiency is a key consideration.
