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.


Adam From has worked in the semiconductor industry for 13+ years. Throughout his career he has focused on memory subsystems from load/store unit verification and multi-processor coherency to scalable interconnect protocols for server-class products. He joined ARM in 2010 to leverage his expertise in these areas as they expand to new market segments. Adam earned his MS and BS degrees in ECE from Carnegie Mellon University in 2001.
