マイクロソフトが次期 Windows OS のARMベースを含むSoCアーキテクチャサポートを正式に発表しました。組み込み版のWindowsは従来からARMプロセッサに対応していますが、今回発表されたのは単に「the next version of Windows」。つまり現在は仮にWindows 8と呼ばれる次期OSを指しています。「ARMベースを含むSoCアーキテクチャ」と書かれているのは、x86ベースのSoCも含んでいるため。インテルやAMDの x86ベース SoC については、「ネイティブx86アプリの実行」を含めフルにWindows をサポートすると表現されています。
次期WindowsがサポートするSoCのメーカーとして発表文に挙げられているのは、x86がインテルとAMD、ARMベースがNVIDIA、Qualcomm、TI。本日午後におこなわれるCESキーノートでは、ARMネイティブで動くMicrosoft Office も実演される予定です。マイクロソフトがARM版のフルWindowsを発表するらしい、とのうわさ
は先月末にBloomberg や WSJが報じていたとおり。x86版とARM版の違いを含め、詳細はわかりしだい更新してゆきます。続きはマイクロソフトの発表文と各社のコメント。
Microsoft Announces Support of System on a Chip Architectures From Intel, AMD, and ARM for Next Version of Windows
January 5, 2011
LAS VEGAS - Jan. 5, 2011 - Microsoft Corp. today announced at 2011 International CES that the next version of Windows will support System on a Chip (SoC) architectures, including ARM-based systems from partners NVIDIA Corp., Qualcomm Inc. and Texas Instruments Inc. On the x86 architecture, Intel Corporation and AMD continue their work on low-power SoC designs that fully support Windows, including support for native x86 applications. SoC architectures will fuel significant innovation across the hardware spectrum when coupled with the depth and breadth of the Windows platform.
At today's announcement, Microsoft demonstrated the next version of Windows running on new SoC platforms from Intel running on x86 architecture and from NVIDIA, Qualcomm and Texas Instruments on ARM architecture. The technology demonstration included Windows client support across a range of scenarios, such as hardware-accelerated graphics and media playback, hardware-accelerated Web browsing with the latest Microsoft Internet Explorer, USB device support, printing and other features customers have come to expect from their computing experience. Microsoft Office running natively on ARM also was shown as a demonstration of the full depth and breadth of Windows platform capabilities on ARM architecture.
Windows will continue its industry-leading support across the widest possible set of devices, delivering the breadth and choice that customers demand. Intel and AMD continue to evolve and improve the x86 platforms, including new low-power systems, and advance new designs such as the recently announced 2nd Generation Intel® Core™ processor family and AMD's Fusion accelerated processing units (APUs). NVIDIA, Qualcomm and Texas Instruments are joining Microsoft to provide ARM-based designs for the first time.
"With today's announcement, we're showing the flexibility and resiliency of Windows through the power of software and a commitment to world-class engineering. We continue to evolve Windows to deliver the functionality customers demand across the widest variety of hardware platforms and form factors," said Steven Sinofsky, president of the Windows and Windows Live Division at Microsoft.
SoC architectures consolidate the major components of a computing device onto a single package of silicon. This consolidation enables smaller, thinner devices while reducing the amount of power required for the device, increasing battery life and making possible always-on and always-connected functionality. With support of SoC in the next version of the Windows client, Microsoft is enabling industry partners to design and deliver the widest range of hardware ever.
Founded in 1975, Microsoft (Nasdaq "MSFT") is the worldwide leader in software, services and solutions that help people and businesses realize their full potential.
