UEFI requires the firmware and operating system loader (or kernel) to be size-matched; that is, a 64-bit UEFI firmware implementation can load only a 64-bit operating system (OS) boot loader or kernel (unless the CSM-based legacy boot is used) and the same applies to 32-bit.
ARMv8-A allows 32-bit applications to be executed in a 64-bit OS, and a 32-bit OS to be under the control of a 64-bit hypervisor. [4] ARM announced their Cortex-A53 and Cortex-A57 cores on 30 October 2012. [5] Apple was the first to release an ARMv8-A compatible core in a consumer product .
This is a list of products using processors (i.e. central processing units) based on the ARM architecture family, sorted by generation 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.
One of the biggest limitations of the Windows on Snapdragon platform is its inability to run 64-bit apps. Microsoft has said on multiple occasions that it intends to eventually offer that support ...

ARM supports 32-bit × 32-bit multiplies with either a 32-bit result or 64-bit result, though Cortex-M0 / M0+ / M1 cores do not support 64-bit results. [109] Some ARM cores also support 16-bit × 16-bit and 32-bit × 16-bit multiplies. The divide instructions are only included in the following ARM architectures:
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. In 2005, ARM provided a summary of the numerous vendors who implement ARM cores in their design. [ 1 ]
