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 ...
AArch64 or ARM64 is the 64-bit Execution state of the ARM ... The latter instruction sets provide user-space compatibility with the existing 32-bit ARMv7-A architecture.

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.
ARM core technical reference manual; ARM architecture reference manual; Microchip has additional documents, such as: evaluation board user manuals, application notes, getting started guides, software library documents, errata, and more. See External Links section for links to official Microchip and ARM documents.
The ARM Cortex-A is a group of 32-bit and 64-bit RISC ARM processor cores licensed by Arm Holdings.The cores are intended for application use. The group consists of 32-bit only cores: ARM Cortex-A5, ARM Cortex-A7, ARM Cortex-A8, ARM Cortex-A9, ARM Cortex-A12, ARM Cortex-A15, ARM Cortex-A17 MPCore, and ARM Cortex-A32, 32/64-bit mixed operation cores: ARM Cortex-A35, ARM Cortex-A53, ARM Cortex ...
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.
The reference design supports up to 64 or 128 Neoverse N1 cores. [17] [18] Notable changes from the Cortex-A76: Coherent I-cache and D-cache with 4-cycle LD-use; L2 cache: 512–1024 KB per core; Mesh interconnect instead of 1–4 cores per cluster; Neoverse N1 implements the ARMv8.2-A instruction set.
