LG has acquired 10% of the shares of ARM Holdings, becoming a preferred partner of the company. This assumes that the Korean giant will have chip production license based on the most advanced architecture that comes out of the investigations of the British company. Specifically, your privilege will be on the line of Cortex-A50 cores based on ARMv8 architecture having 64-bit support, manufactured to 20 nm and that offer solutions for both high performance and autonomy.
From soon those of LG will be able to start preparing SoCs that include cores Cortex-A57, high power, and Cortex-A53, low power consumption. You will also have access to new generations of Mali T67x and T62X graphics processors.
This chips could follow the principle of big.LITTLE configuration combining the two types of nuclei, thus being able to offer the qualities of both in the same team. This principle is already followed by Samsung's Exynos 5 Octa that we find in half of the Galaxy S4 but in this case combining the high-performance Cortex-A15 cores with the low-power Cortex-A7.
These own LG chips could begin to arrive from 2014 and it is expected that it is in tablets where we will see them debut. Licensing of the Cortex-A50 cores has been moving around for a while now, but no chips are expected to use them on the market until the end of this year.
With support for 64 bits it will be possible to implement more than 4 GB of RAM without the need to use PAE (Physical Address Extension).
In the previous graph we can see the improvement in performance and energy savings that we can expect from the implementation of this type of core and architecture. We could talk about more than double the performance and half the battery consumption that we find today on chips with Cortex-A15 and Cortex-A7 configured according to big.LITTLE.
