The instructions are added in vector and scalar forms. A set of AArch64 load and store instructions that can provide memory access order that is limited to configurable address regions. The optional CRC instructions in v8.0 become a requirement in ARMv8.1. Enhancements for the exception model and memory translation system included the following:
The RISC-V instruction set refers to the set of instructions that RISC-V compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
Since 1995, various versions of the ARM Architecture Reference Manual (see § External links) have been the primary source of documentation on the ARM processor architecture and instruction set, distinguishing interfaces that all ARM processors are required to support (such as instruction semantics) from implementation details that may vary ...
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 ]
A typical top-down documentation tree is: manufacturer website, manufacturer marketing slides, manufacturer datasheet for the exact physical chip, manufacturer detailed reference manual that describes common peripherals and aspects of a physical chip family, ARM core generic user guide, ARM core technical reference manual, ARM architecture ...

The ARM Cortex-A72 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Austin design centre. The Cortex-A72 is a 3-way decode out-of-order superscalar pipeline. [1]
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 ...
