Every year, Arm releases extensions to its main architecture, in order to regularly release new features in support of partner needs. In this guide, we explained the extensions to the Armv8.x architecture, described how to read and use the extensions, and outlined some of the features that the extensions support.

After reviewing this guide, you should understand how the extensions are expressed, which features are available in which extensions, and how to determine which features an Arm Cortex CPU implementation supports.

To keep learning about the Armv8-A architecture, see more in our series of guides.
