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. [ 2 ]
AArch64/A64 and AArch32/A32 use 32-bit instructions, AArch32/T32 (Thumb-2) uses mixed 16- and ... [212] Windows 11 runs native ARM64 apps and can also run x86 and x86 ...

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 ]
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
ARM also introduced a second integer multiply unit in the execution unit and an additional load Address Generation Unit (AGU) to increase both the data load and bandwidth by 50%. Other optimizations of the chipset include fused instructions [5] and efficiency improvements to instruction schedulers, register renaming structures, and the re-order ...
The assembly instruction nop will most likely expand to mov r0, r0 which is encoded 0xE1A00000 (little-endian architecture). [4] ARM T32 (16 bit) NOP: 2 0xb000 Opcode for ADD SP, #0 - Add zero to the stack pointer (No operation). The assembly instruction nop will most likely expand to mov r8, r8 which is encoded 0x46C0. [5] ARM T32 (32 bit) NOP ...
On Intel processors, the technique is known as Indirect Branch Tracking (IBT), with the "end branch" instructions endbr32 and endbr64 acting as the branch target instructions for 32 and 64 bit mode respectively. [1] [2] IBT is part of the Intel Control-Flow Enforcement Technology first released in the Tiger Lake generation of processors. [3]
