Today’s mobile application processors need to strike a fine balance between single-thread, multi-thread, thermally-constrained high-intensity and low-intensity workloads. They need to also provide higher levels of performance, better user-experience and a longer battery life. big.LITTLE heterogeneous multi-processing (HMP), consisting of high-performance “big” cores coupled with low-power “LITTLE” cores, allow a diverse mix of modern workloads to run on the most appropriate cores. As big.LITTLE continues to evolve, full HMP operation is becoming standard, the arrival of 2+4 topologies add to the diversity of supported options and the software has extended to support 64-bit on ARMv8. In this talk, we will showcase measured performance and power-savings on the latest big.LITTLE based solutions.
