Samsung demonstrates ARM's big.LITTLE architecture


Rumors of an upcoming octa-core processor based SoC were floating arounf for a long time but Samsung gave all of them a successful hault when they officially announced an octa-core processor based Exynos 5 SoC during this year's CES. While it was told that it will be based on ARM's big.LITTLE architecture technology - 4 A7 cores for light daily tasks combined with 4 A15 cores for demanding tasks baked into one chipset - but a very few people knew how it works. Samsung has just resolved the awareness issue.


If you know about NVIDIA's Tegra 3 and Tegra 4 chipset works with their 4+1 configuration, than you should know its pretty much based on that only. The set of lower performing cores carry out the daily low demanding tasks for the users whereas the high performing set kicks in when the users needs high performance and all the switching is enabled by MP scheduler which intelligently analyzes and assigns the task to the right set.

To help with the understanding, a visual demonstration was all uploaded on YouTube. In the video, the processor showcased comprises of 3 A7 based cores(low performing set) and 2 A15 cores(high performing set) in the big.LITTLE configuration. Lets have a look at the video to understand the process better.
