Exynos is a series of ARM-based System-on-Chips (SoCs) developed and manufactured by Samsung Electronics and is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs. == History == In 2010 Samsung launched the S5PC110 (now Exynos 3 Single) in its Samsung Galaxy S mobile phone, which featured a licensed ARM Cortex-A8 CPU. In early 2011, Samsung first launched the Exynos 4210 SoC in its Samsung Galaxy S II mobile smartphone. The driver code for the Exynos 4210 was made available in the Linux kernel and support was added in version 3.2 in November 2011.〔(【引用サイトリンク】title= Linux 3.2 DriverArch Linux kernel 3.2 support Exynos 4210 - Linux Kernel Newbies )〕 On 29 September 2011, Samsung introduced Exynos 4212〔(【引用サイトリンク】title= Samsung Unveils its Next High-Performance Application Processor for Smartphone and Tablet Devices )〕 as a successor to the 4210; it features a higher clock frequency and "50 percent higher 3D graphics performance over the previous processor generation".〔(【引用サイトリンク】title=Exynos News )〕 Built with a 32 nm High-K Metal Gate (HKMG) low-power process; it promises a "30 percent lower power-level over the previous process generation." On 30 November 2011, Samsung released information about their upcoming SoC with a dual-core ARM Cortex-A15 CPU, which was initially named "Exynos 5250" and was later renamed to Exynos 5 Dual. This SoC has a memory interface providing 12.8 GB/s of memory bandwidth, support for USB 3.0 and SATA 3, can decode full 1080p video at 60 fps along with simultaneously displaying WQXGA-resolution (2560x1600) on a mobile display as well as 1080p over HDMI.〔(【引用サイトリンク】title= Application Processor Product Catalogue )〕 On 26 April 2012, Samsung released the Exynos 4 Quad, which powers the Samsung Galaxy S III and Samsung Galaxy Note II. The Exynos 4 Quad SoC uses 20% less power than the SoC in Samsung Galaxy SII. Samsung also changed the name of several SoCs, Exynos 3110 to Exynos 3 Single, Exynos 4210 and 4212 to Exynos 4 Dual 45 nm,〔(【引用サイトリンク】title=Exynos 4 Dual 45nm )〕 and Exynos 4 Dual 32 nm〔(【引用サイトリンク】title=Exynos 4 Dual 32nm )〕 and Exynos 5250 to Exynos 5 Dual. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Exynos」の詳細全文を読む スポンサード リンク
