ARM64EC – A new way of building apps for Windows 11 on Arm

Microsoft launched Windows 11 in October 2021. Windows 11 includes a novel feature for native Windows on Arm (WoA) application support, ARM64EC. ARM64EC is a new way of building native apps that allows a “transition to native performance on Arm”. It runs at native speed but is also interoperable with x64 format. This means that developers can move their x64 code incrementally to ARM64EC, where previously with ARM64 all their code had to be ported at once. This allows developers to prioritize porting of performance-critical code to ARM64EC. This new technology is important for the WoA ecosystem. This session will cover (1) how ARM64EC is implemented and why, and (2) study results with OpenCV, well-known computer vision library.
