Samsung “Fixes” Exynos 5 Octa CPU

Samsung’s 8 core Exynos Octa 5 CPU is available in several phones as well as the “phablet” Galaxy Note 3. It uses ARM’s big.Little technology, pairing a power-saving, lower performance quad-core A7 cpu with a high performance quad-core A15. Depending on the load, one set of cores or the other is used at any one time.  While this may seem like a good way to save battery life, it’s not a very efficient implementation of the eight available cores.

Evidently Samsung realized this also.  It has announced the upcoming launch of Heterogeneous Multi-Processing (HMP).  As the name implies, utilizing HMP, the Octa 5 will be able to run any number of cores, in any combination of A7 and A15 simultaneously.  With the current configuration, if a 3D game is using the A15 core set, any background tasks not really needing the computational power of the A15 cpu are still forced to use it.  Now with HMP, one to four A7 cores can take care of these low priority demands, leaving the more capable A15 cores to do the heavy computing.  Available in the 4th quarter, one thing that remains unclear is whether the HMP technology can be applied to existing devices via a software update, or if it requires specific hardware implementation as well.
