Samsung has announced Heterogeneous Multi-Processing functionality to its Exynos 5 Octa. This allows all eight core at the same time be put to work. It is unclear whether the current generation of soc’s is an upgrade.
According to Samsung will have the Exynos 5 Octa is the most powerful usage model of the big.Little concept of ARM, support for Heterogeneous Multi-Processing to add. With the concept of ARM will have soc’s four powerful but energy-gulping Cortex A15 processing cores, in addition to four more fuel-efficient, but less powerful Cortex A7 cores. At the current Exynos 5 Octa chips was not yet possible for the workload across all cores to distribute, but that opportunity comes in the fourth quarter of this year.
Software that is a lot of processing requests is then processed by the four Cortex A15 cores while threads with less priority by the four efficient cores can be dealt with. Essential for this distribution is the software-implementation, that the distribution of the threads across the cores controls.
It is unclear whether the current Exynos 5410, which is in Galaxy S4 models in some regions, also the HMP update, but probably is not. Previously appeared messages that the Exynos 5410 does not have a correct functioning of the required cache coherrent interconnect. Samsung has this bug, however, never confirmed. Probably brings Samsung the functionality to the end of July announced Exynos 5 Octa Evolved. Also in that period, announced the MediaTek MT8135 does have heterogeneous multi-processing using ARM’s big.Little technology use.
