AArch64 or ARM64 is the 64-bit Execution state of the ARM architecture family. It was first introduced with the Armv8-A architecture, and has had many extension updates. [ 1 ]
An ARMv8-A processor can support one or both of AArch32 and AArch64; it may support AArch32 and AArch64 at lower Exception levels and only AArch64 at higher Exception levels. [162] For example, the ARM Cortex-A32 supports only AArch32, [163] the ARM Cortex-A34 supports only AArch64, [164] and the ARM Cortex-A72 supports both AArch64 and AArch32 ...
This is a list of central processing units based on the ARM family of instruction sets designed by ARM Ltd. and third parties, sorted by version of the ARM instruction set, release and name.
This is a table of 64/32-bit central processing units that implement the ARMv8-A instruction set architecture and mandatory or optional extensions of it. Most chips support the 32-bit ARMv7-A for legacy applications.

In the early 2020s, Apple Inc. transitioned its line of Mac computers from designs using Intel x86-64 CPUs to designs based on Apple-designed processors based on the ARM64 architecture.
The ARM AArch64 Virtual Memory System Architecture allows from 48 to 56 bits for virtual memory and, for any given processor, from 32 to 56 bits for physical memory. [ 31 ] The DEC Alpha specification requires minimum of 43 bits of virtual memory address space (8 TB) to be supported, and hardware need to check and trap if the remaining ...
And, according to the Arm Architecture Reference Manual Supplement - Armv8, for Armv8-R AArch64 architecture profile, section B1.1: The Armv8-R AArch64 application level programmers’ model differs from the Armv8-A AArch64 profile in the following ways: Armv8-R AArch64 supports only a single Security state, Secure. EL2 is mandatory.
