<span class="mw-page-title-main">ARM big.LITTLE</span> Heterogeneous computing architecture

ARM big.LITTLE is a heterogeneous computing architecture developed by ARM Holdings, coupling relatively battery-saving and slower processor cores (LITTLE) with relatively more powerful and power-hungry ones (big). The intention is to create a multi-core processor that can adjust better to dynamic computing needs and use less power than clock scaling alone. ARM's marketing material promises up to a 75% savings in power usage for some activities. Most commonly, ARM big.LITTLE architectures are used to create a multi-processor system-on-chip (MPSoC).
