big.LITTLE

(redirected from ARM big.LITTLE)

big.LITTLE

An ARM-based multicore CPU that uses one or more pairs of high-power and low-power "virtual cores" for greater battery life. Depending on the processing demand, either the big or little core is used. The big.LITTLE architecture was introduced in 2011 along with the first low-power Cortex A7 CPU that was designed to be paired with the high-power A15. The ARM 53-57 pair was announced subsequently.

Why Not BIG.little?
While the obvious upper/lower case designation for this would be BIG.little, somebody thought big.LITTLE would be more ingenious. Go figure. See ARM and Exynos 5 Octa.

"ARM big.LITTLE multi-processing technology delivers the highest performance and efficiency across the widest range of workloads and it is a significant endorsement to see it used in the new Google Chromebook," said Nandan Nayampally, vice president of marketing, CPU group, ARM.
Samsung used the ARM big.LITTLE architecture on Galaxy Note 3 Neo and it allows the device to be powered by dual-core 1.7 GHz Cortex A-15 and quad-core 1.3 GHz Cortex-A7 to run all active and background apps.
Noel Hurley, Vice President, Strategy and Marketing, Processor Division, ARM said that, "ARM big.LITTLE technology reduces processor energy consumption by up to 70 percent on common workloads, which is critical in the drive towards all-day battery life for mobile platforms," said.
'Being able to implement Full Profile GPU Compute in conjunction with ARM big.LITTLE processing configurations will be a key driver to the overall performance and capabilities of our devices.'
The Exynos variant will also see better power efficiency due to its (http://www.arm.com/products/processors/technologies/biglittleprocessing.php) ARM big.LITTLE technology.
The Exynos 5 Octa variant will also see better power efficiency due to its ARM big.LITTLE technology.
