ARM's big.LITTLE architecture introduces a solution to optimize power consumption by selecting the core type most suitable for a level of processing load along with high performance. Using heterogeneous multi-core processing having high performance cortex-A15 with power efficient cortex-A7 is what big.LITTLE architecture follows to have power efficient system on-chip which is demanded by today's smart phones. For smooth functioning and effective data transferring big.LITTLE uses GIC-400 and CCI-400 interfaces to interface between two processors.
