Heterogeneous Multi-Processing Solution of Exynos 5 Octa with ARM big.LITTLE Technology
With an increasing need for higher performance in mobile devices, the battery capacity must be increased accordingly, which is not easy because of the small size of mobile devices. Therefore, the demand for better power efficiency of mobile devices, which implies lower power consumption and higher performance is becoming critical. Recently, big.LITTLE architecture was introduced to fulfill the demand. A few solutions are available to be implemented in the big.LITTLE architecture. This paper introduces Heterogeneous Multi-Processing (HMP) solution that is more power-efficient than the cluster switching solution ported in several mobile devices in the current market.
