Samsung Exynos8890 secret weapon: +Janus engine-driven research SCI schema Samsung S7, S7 Samsung Edge, Samsung Galaxy S7-IT information
IT information news on March 14, international version of the Samsung Galaxy S7/S7 Edge Exynos8890 processor used in the launch was the attention of the parties, and ran is also notable, however, as Samsung's first independent research and development what are the characteristics of SOC,Exynos8890, which is what architecture? At present, the SamMobile as we reveal the mystery.
As far as SamMbile said, Samsung Electronics recently put into mass production Exynos 8 OCTA CPU core developed by Exynos M1 for the first time, shows technical capabilities of Samsung's Semiconductor Division has increased significantly. According to Korean media reports inews24, Exynos 8890 to SCI developed instead of using the raised ARM CoreLink CCI-400 attention. People in the industry said, after independently researched the CPU core, Samsung Electronics, and carries its own patented technology SCI, next to their own patented technology developed chipsets.

Samsung is engaged after the Smartphone era and actively promote deep learning (Deep Learning) research and development, developed the graphics processor (GPU) and this is not unrelated. Because of the more exclusive design patent on the AP, you can reduce when developing new chipset, reducing licensing fees must be paid, and freeing up your budget for research and development.
Samsung MWC2016 display Exynos 8890 adopted the new Janus, also sparked curiosity. Samsung side note, Exynos 8 OCTA through Janus engine performance can be better than Exynos 7 upgrade 30%, and announced that it would apply to future new chipset.
Due to start using the new Samsung Exynos 8890 driving mode of the CPU core, so some traders also speculated that the technique is known as Janus. In fact, Exynos 8890 uses 64-bit ARM V8 architecture, to design 4 Exynos M1 core and 4 core ARM Cortex-A53 composition. Unlike Exynos 7420 workload increases, A53, low power consumption and high performance A57 started,M1 new technologies used in the normal driving 2 core frequency of 2.6GHz, when a heavy task, then changed to driving a 4-core 2.3GHz.

IT资讯讯 3月14日消息，三星在Galaxy S7/S7 Edge国际版中所使用的Exynos8890处理器一经推出受到了各方的瞩目，并且跑分情况也可圈可点，但是作为三星第一款自主研发的SOC，Exynos8890有什么特点，其中采用的是什么架构？目前，SamMobile为我们揭示了其中的奥秘。
据SamMbile所说，三星电子最近投入量产Exynos 8 OCTA首度采用自主研发的CPU核心Exynos M1，显示三星半导体部门的技术能力大幅提升。据韩媒inews24报导，Exynos 8890以自主研发的SCI取代以往使用的ARM CoreLink CCI-400引发瞩目。业界人士表示，三星电子继自主研发设计的CPU核心之后，又搭载了应用自家专利技术的SCI，接下来将以自家专利技术开发芯片组。

三星为迎战后智能型手机时代，积极推动深度学习(Deep Learning)的相关研发，自主研发绘图处理器(GPU)也与此不无关系。因为取得更多关于AP的独家设计专利，就可以降低开发新芯片组时，减少必须支付的专利授权费，也能省下更多预算用于研发。
三星在MWC2016中展示Exynos 8890采用的新技术Janus，也引发外界好奇。三星方面说明，透过Janus引擎Exynos 8 OCTA的性能可以比Exynos 7提升30%，并宣布将应用于未来新上市的芯片组。
由于三星自Exynos 8890就开始使用新的CPU核心驱动方式，因此部分业界人士也猜测该技术就是所谓的Janus。实际上，Exynos 8890采用64位元ARM v8架构，以自主设计的4颗Exynos M1核心与4颗ARM Cortex-A53核心组成。不同于Exynos 7420作业量增加时，会将低功耗的A53与高性能A57全部启动，M1使用的新技术在平常只驱动2颗频率为2.6GHz的大核心，当任务繁重时候，则改以驱动4颗2.3GHz核心。
