Announcing ARM64EC for Windows 11 on ARM

Today, we’re announcing ARM64EC (“Emulation Compatible”), a new way to build apps for Windows 11 on ARM. With the latest Visual Studio tools in preview and the Windows 11 Insider SDK, you’ll be able to take advantage of ARM64EC to incrementally transition your app to running with native speed on ARM, even if you have dependencies or plugins that don’t support ARM yet.

About ARM64EC

ARM64EC is a new application binary interface (ABI) for Windows 11 on ARM that runs with native speed and is interoperable with x64. An app, process, or even a module can freely mix and match ARM64EC and x64 as needed. The ARM64EC code in the app will run natively while any x64 code will run using Windows 11 on ARM’s built-in emulation.

The ARM64EC ABI differs slightly from the existing ARM64 ABI in ways that make it binary compatible with x64 code. Specifically, the ARM64EC ABI follows x64 software conventions including calling convention, stack usage, and data alignment, making ARM64EC and x64 interoperable. Apps built as ARM64EC may contain x64 code but do not have to, since ARM64EC is its own complete, first-class ABI for Windows.

Developer Benefits

Traditionally, rebuilding an app for ARM has meant recompiling the entire app. The result is a great native experience for the customer that unlocks the full power of the ARM device. However, from a developer perspective, porting an app can be all-or-nothing, since all the binaries within a process need to be rebuilt before a customer can see the benefit.

With ARM64EC, you can choose to start small and build incrementally. You can identify a part of your codebase that would benefit most from native performance and rebuild it as ARM64EC. The rest of the app will remain fully functional as emulated x64, but the recompiled ARM64EC parts will now have native speed. Over time, you can recompile more of the app as ARM64EC to further improve performance and conserve battery life for your app’s customers.

The ability to mix and match x64 and ARM64EC makes it possible to build an app for Windows 11 on ARM even if it depends on x64 code outside of your control. Projects with third-party dependencies that don’t support ARM can leave them as x64. And apps with an in-proc plugin ecosystem can build as ARM64EC to get native speed, while continuing to load and use x64 plugins.

Conclusion

We’re motivated by the potential of ARM64EC and excited to see the kinds of apps developers can build for Windows 11 on ARM using this technology. Internally, we’ve rebuilt the binaries of Windows 11 on ARM itself with ARM64EC so that any system code loaded by x64 apps runs with native speed. In addition, the Office team is using ARM64EC in the coming 64-bit Office for ARM so that existing x64 plugins will work seamlessly.

You can get started with ARM64EC by downloading the latest Windows Insider SDK and Visual Studio Preview, then following the steps on docs.microsoft.com to add an ARM64EC configuration. Looking forward, we’ll have more content to share as we walk through in more detail how to take advantage of ARM64EC in your apps.

N97 with ARM 11 or not?????????

Hello people!

Does anybody knows whar procesor it will be on N97?

Because there are rumours that will not be ARM 11,and it will be something much better(i hope). :smileytongue:

Introducing x64 emulation in preview for Windows 10 on ARM PCs

Today, we’re releasing the first preview of x64 emulation for ARM64 devices to Windows Insiders in the Dev Channel starting with the Build 21277. It can be installed on Windows 10 on ARM PCs by following the instructions as explained in this blog post.

When we first launched Windows 10 on ARM in late 2017, the long tail of apps customers needed were dominated by 32-bit-only x86 applications, so we focused our efforts on building an x86 emulator that could run the broad ecosystem of Windows apps seamlessly and transparently. Over time, the ecosystem has moved more toward 64-bit-only x64 apps and we’ve heard the feedback that customers would like to see those x64 apps running on ARM64. That’s why we are working on expanding the capability of our emulation to include x64 applications and sharing this first preview to gather feedback.

While we’re expanding the capabilities of our emulator, for the best possible experience we recommend developers support their apps natively on ARM64. ARM64 apps are fully supported in our Windows SDK and Visual Studio 2017 onwards, and we encourage our developers to recompile their apps for ARM64.

In this preview, you can install x64 apps from the Microsoft Store or from any other location of your choosing. You can try key x64-only productivity apps like Autodesk Sketchbook, as well as games like Rocket League. Other apps, like Chrome, which run today on ARM64 as 32-bit apps, can run as 64-bit using the new x64 emulation capability. These apps may benefit from having more memory when run as 64-bit emulated apps.

In the spirit of the Dev Channel, this capability is still in development and will continue to improve in both compatibility and performance over time, so some of the apps you try running in emulation may not work initially. As you test and try the build, share your feedback with us on the experience in Windows Feedback Hub by using the subcategory x64 Apps on ARM. Your feedback will play a key role in ensuring we are aware of the scenarios most important to you so we can focus on refining them as we provide updates in the coming months.

For the best app performance, please install a preview version of the Qualcomm Adreno graphics driver from the following locations:

Samsung Galaxy Book S: https://aka.ms/x64previewdriver

Lenovo Flex 5G: https://aka.ms/x64previewdriver

Surface Pro X: https://aka.ms/x64previewdriverprox

Additionally, to support running both ARM64 and x64 C++ applications at the same time, please install a preview version of the ARM64 C++ redistributable from https://aka.ms/arm64previewredist. These steps will not be required in future Insider Preview builds.

With developers increasingly supporting ARM64 apps natively, emulating x64 apps is an important step in our journey with Windows 10 on ARM. Through working with Qualcomm Technologies, Windows 10 on ARM PCs continue to deliver incredible battery life, connectivity capabilities with 4G LTE and 5G, and immersive experiences with AI acceleration, pen and touch capabilities – all features we believe to be more essential as we work, learn, and connect from home and other remote locations.

From the unveiling of new Windows 10 on ARM devices like the Acer Spin 7, the Lenovo Flex 5G and the new Surface Pro X, to the announcement of compatibility on ARM through App Assure, the releases of ARM64-native Microsoft Teams, a fully optimized browsing experience with native Microsoft Edge, to the OpenGL/OpenCL compatibility layer, and the beta version of ARM64-native Photoshop as well as ARM64-native Adobe Lightroom that was released this week – we are committed to listening to customer feedback to ensure Windows 10 on ARM provides a great customer experience.

We look forward to the feedback from our Windows Insider community. If you’d like to try the emulation preview and are not yet part of the Windows Insider Program you can join here.
