Intel Atom is the brand name for a line of ultra-low-voltage IA-32 and x86-64 CPUs (or microprocessors) from Intel, originally designed in 45 nm complementary metal–oxide–semiconductor (CMOS) with subsequent models, codenamed ''Cedar'', using a 32 nm process. Atom is mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, and mobile Internet devices (MIDs). The first generation of Atom processors are based on the Bonnell microarchitecture. On 21 December 2009, Intel announced the ''Pine Trail'' platform, including new Atom processor code-named ''Pineview'' (Atom N450), with total kit power consumption down 20%. On 28 December 2011, Intel updated the Atom line with the ''Cedar'' processors.〔 In December 2012, Intel launched the 64-bit ''Centerton'' family of Atom CPUs, designed specifically for use in servers. ''Centerton'' adds features previously unavailable in Atom processors, such as Intel VT virtualization technology and support for ECC memory. On 4 September 2013 Intel launched a 22 nm successor to ''Centerton'', codenamed ''Avoton''.〔(Inside Intel's Atom C2000-series 'Avoton' processors ) 〕 In 2012, Intel announced a new system on chip (SoC) platform designed for smartphones and tablets which would use the Atom line of CPUs.〔(Intel Raises Bar on Smartphones, Tablets and Ultrabook™ Devices )〕 It is a continuation of the partnership announced by Intel and Google on 13 September 2011 to provide support for the Android operating system on Intel x86 processors.〔(Antara News : Intel, Google announce partnership for Android smartphones )〕 This range competes with existing SoCs developed for the smartphone and tablet market from companies like Texas Instruments, Nvidia, Qualcomm and Samsung. == History == Intel Atom is a direct successor of the Intel A100 and A110 low-power microprocessors (code-named Stealey), which were built on a 90 nm process, had 512 kB L2 cache and ran at 600 MHz/800 MHz with 3 W TDP (Thermal Design Power). Prior to the Silverthorne announcement, outside sources had speculated that Atom would compete with AMD's Geode system-on-a-chip processors, used by the One Laptop per Child (OLPC) project, and other cost and power sensitive applications for x86 processors. However, Intel revealed on 15 October 2007 that it was developing another new mobile processor, codenamed Diamondville, for OLPC-type devices. "Atom" was the name under which Silverthorne would be sold, while the supporting chipset formerly code-named Menlow was called Centrino Atom. At Spring Intel Developer Forum (IDF) 2008 in Shanghai, Intel officially announced that Silverthorne and Diamondville are based on the same microarchitecture. Silverthorne would be called the Atom Z5xx series and Diamondville would be called the Atom N2xx series. The more expensive lower-power Silverthorne parts will be used in Intel mobile Internet devices (MIDs) whereas Diamondville will be used in low-cost desktop and notebooks. Several Mini-ITX motherboard samples have also been revealed. Intel and Lenovo also jointly announced an Atom powered MID called the IdeaPad U8. In April 2008, a MID development kit was announced by Sophia Systems and the first board called CoreExpress-ECO was revealed by a German company LiPPERT Embedded Computers, GmbH. Intel offers Atom based motherboards. In December 2012, Intel released Atom for servers, the S1200 series. The primary difference between these processors and all prior versions, is that ECC memory support has been added, enabling the use of the Atom in mission-critical server environments that demand redundancy and memory failure protection. 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「Intel Atom (CPU)」の詳細全文を読む スポンサード リンク
