big.LITTLE is a heterogeneous processing architecture that uses two types of processor.
ARM Technologies
-
-
NEON is a SIMD architecture extension for the ARM Cortex-A series and Cortex-R52 processors.
-
ARM’s low-power Cortex processors address a wide range of signal processing applications.
-
ARM Mali Technologies have been developed to allow increasingly more complex graphics within the power capacity and thermal limit of mobile devices. All formats provide significant system-wide bandwidth reductions to ensure that end-users are able to experience the latest in graphics quality on any device. Mali Technologies include Adaptive Scalable Texture Compression (ASTC), ARM Frame Buffer Compression (AFBC), Transaction Elimination (TE) and Smart Composition.
