big.LITTLE is a heterogeneous computing technology from ARM which associates or pairs high-performance cores (to achieve peak execution speed) with low-power core (to achieve low-power idle state). big.LITTLE was announced in 2011 and was presented as a commercial product for the first time by Samsung at CES 2013 when the company demonstrated its Exynos 5 Octa chip which includes four Cortex A15 cores and four Cortex A7 cores.
