Just after the emergence of the four core technology, the news of the eight core technology has been spread, which makes people exclaim the rapid development of science and technology. Recently, it was reported that Samsung was preparing to launch a more powerful ARM based big Eight core processors with LITTLE (large and small cores) structure can achieve a better balance between performance and power consumption. At present, this plan has been put on the agenda, and the eight nuclear products will probably be announced at the international solid-state circuit conference on February 19 next year.
Big. LITTLE size core structure
Big and small core architecture of big.LITTLE is a solution for performance and power consumption proposed by ARM Corporation. Big.LITTLE combines the performance of ARM Cortex-A15 MPCore processor with the energy-saving effect of Cortex-A7 processor, enabling the same application software to seamlessly switch between them. By selecting the best processor for each task, big.LITTLE can theoretically extend the service life of the battery by up to 70%. In addition, the overall size of the Cortex-A7 processor based on the 28 nanometer architecture is even five times smaller than that of the Cortex-A8 processor, but its performance will be higher.
In the previous popular science article "Comprehensive Summary of ARM Mobile Phone Processors", we summarized that in addition to Cortex-A15 and Cortex-A7, Cortex-A53 and Cortex-A57 that have not yet been released can also use big LITTLE structure to further balance power consumption and performance.
How is the Samsung eight core constituted?
Samsung eight core will adopt 28nm process, based on big The LITTLE big and small core structure is mainly composed of two parts: the first part is a 1.8GHz quad core Cortex-A15 processor, which is used to deal with heavy computing tasks, such as games, intensity computing, etc., to highlight performance; The second part is a 1.2 GHz quad core Cortex-A7 processor, which is used to deal with lightweight tasks such as standby, such as browsing the web, listening to music, and focusing on power consumption.
Introduction to the development of Samsung processors
Samsung processors have a great influence in the industry. At present, dual core/quad core Exynos 4 and dual core Exynos 5 are widely used. In addition, quad core Exynos 5 is rumored to be applied soon.
Starting from the Hummingbird processor of Samsung I9000, Samsung's home-made processor has left a deep impression. To the Exynos 4210 of I9100, the Exynos brand has been deeply rooted in the hearts of the people. The Samsung Exynos 4412 used in the next I9300 and Note II has now become one of the most influential processor products in the industry, and has won a good reputation for its strong performance. In the new Samsung Chromebook recently released, the Samsung dual core Exynos 5 processor is used for the first time. It uses the Cortex-A15 architecture, but has not been applied to tablets and mobile phones. The next Samsung eight core processor is expected to be used in tablet computers at the beginning, and will appear in more portable mobile devices when it matures.
