Updated processor Exynos 5 Octa will be able to use all eight cores simultaneously





Samsung has announced that its next-generation mobile processor Exynos 5 Octa will support technology Heterogeneous Multi-Processing (HMP), which in turn will use all eight cores simultaneously.

For those who do not understand what is being said, let’s try to explain easier. Some processors and ARM SoC («system on chip) have several independent sets of nuclei. That is in front of you almost double the processor on a single board. A low four cores, for example, Cortex-A7 are used in such a processor to work with non-demanding applications, as well as to the processor face the task more difficult, for example, you run some resource-intensive game or movie in Full HD resolution, then, works the four main powerful core of, say, Cortex-A15.

The problem is that the current processor architecture Exynos 5410 (used Galaxy S4) prevents simultaneous operation include all eight cores. This question should be solved updated architecture ARM big.LITTLE, which supports work in two modes. The first mode is used in the Exynos 5410. In this case, the energy-efficient core Cortex A7 is used by default, disable, and enable inclusion of a more powerful Cortex A15 cores to perform more demanding tasks. The new processor Samsung Exynos 5420 is going to fix the cache subsystem (CCI), which will enable the processor support for HMP.

Not accustomed to the restrictions, the South Korean company is going to provide updated processor Exynos 5 Octa HMP-enabled by the end of this year. An important impetus for this decision are quite possibly the recent news that the “full” eight-core processors introduced the company MediaTek .

If Samsung really wants to provide updated processors in the fourth quarter, the first smartphone with a full eight-core processor will quite possibly Galaxy Note III , a tablet – the new Galaxy Note 10.1 .
