Windows 8 on ARM (woa)

Microsoft said earlier that the new generation of devices using the "Windows 8 on ARM (woa)" architecture will make users feel that there is no gap between the user experience and x86/64 PC. The company said that both woa and x86/64 versions will be released at the same time.
Steven Sinofsky, president of Microsoft Windows, pointed out that woa will bring a "no discount" user experience, and its appearance and practical use will be in line with people's expectations. You can log on using the same method, and start the application using the same method. Program You can also use the new Windows Store in the same way. Similarly, users of these two platforms will see the Brand New Start Screen and Metro-style applications, as well as IE, Windows File explorer, and other external peripherals; if necessary, woa can also allow users to access Windows desktops, providing "the same fast and smooth experience ".
To solve the software compatibility problem of ARM architecture, woa will contain a software package named "office 15", which contains Word, Excel, PowerPoint, and OneNote, it is designed to minimize touch and power consumption, providing users with complete operation functions and file compatibility. Therefore, the Office executed on the ARM architecture will be in the same form as the current application on the PC, rather than the metro style.
Woa is not a completely independent product, which means that you will not be able to install it on any device that uses the ARM architecture. It will be directly installed on the device by the OEM. Different Versions of ARM-based chips will provide completely different user experiences, Steven Sinofsky said, "Every arm-authorized operator will use different methods to develop products, given the unique features of these products, there are different trade-offs during design, and each company will eventually develop a unique silicon chip product." These options, he pointed out, are the key to terminal product differentiation. This is the main reason why Microsoft chose three arm-authorized chip vendors as its partners. The three partners are NVIDIA, Qualcomm, and Texas Instrument ).
To allow windows to run smoothly on the ARM architecture is an extremely difficult engineering challenge. The result is a comprehensive re-architecture from chipset to user experience ". These challenges include setting Metro-style applications, hardware-accelerated HTML5 and IE 10, and "always-connected" networking.
According to Microsoft, woa devices do not need to be shut down, because the operation methods of these devices are as simple as those of mobile phones, and they are in the "connected standby" status. Therefore, the traditional sleep and sleep modes are redundant. Once the woa device is awakened, the user can immediately access the full-load job and immediately use all functions of the entire woa PC. When the screen is dimmed (for example, if the user presses the key or the screen sleep time is reached), The woa PC enters a new ultra-low power supply mode, allowing the battery to use for several weeks. In fact, the woa system dynamically adjusts power consumption and tries its best to find ways to reduce power consumption, such as shutting down unused parts of the system. Not only does the woa device have the "Network Connection standby" function, but Microsoft is working hard to achieve the same function in x86/64 Soc.
Application designers can also use the latest Visual Studio 11 tools (including C #/Vb/XAML and JScript/HTML5 ), develop the required winrt for the woa device (develop the Windows API with the Metro style application ). Native program for winrt Code C and C ++ are also supported, said Sinofsky. However, he admitted that woa does not support execution, simulation, or transplantation of both x86 and 64 desktop applications.
