Moving to 64-bit exclusively is a big deal for Android, developers, and Arm.

Although such a core will continue to provide 32 and 64-bit support to ensure a smooth transition.

The transition to 64-bit only starts with the big Cortex-A CPU cores.

Android introduced 64-bit support with 5.0 Lollipop back in 2014, but Android and Arm’s CPU cores continue to support legacy 32-bit applications.

Speaking at an Arm DevSummit keynote, Paul Williamson, VP and GM of Client Business at Arm, announced that future Arm Cortex-A CPU cores — such as those powering future smartphones — will become 64-bit only come 2022.
