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 Cortex-A5: 8 Multi-core, single issue, in-order ARM Cortex-A7 MPCore: 8 Partial dual-issue, in-order, 2-way set associative level 1 instruction cache ARM Cortex-A8: 2005 13 Dual-issue, in-order, speculative execution, superscalar, 2-way pipeline decode ARM Cortex-A9 MPCore: 2007 8–11 Out-of-order, speculative issue, superscalar ARM Cortex ...
An optional extension to the ARM instruction set in the ARMv5TE, ARMv5TEJ and ARMv6 architectures. VFPv2 has 16 64-bit FPU registers. VFPv3 or VFPv3-D32 Implemented on most Cortex-A8 and A9 ARMv7 processors. It is backward-compatible with VFPv2, except that it cannot trap floating-point exceptions.
The first was the CISC (Complex Instruction Set Computer), which had many different instructions. In the 1970s, however, places like IBM did research and found that many instructions in the set could be eliminated. The result was the RISC (Reduced Instruction Set Computer), an architecture that uses a smaller set of instructions.
This is a comparison of ARM instruction set architecture application processor cores designed by Arm Holdings (ARM Cortex-A) and 3rd parties. It does not include ARM Cortex-R, ARM Cortex-M, or legacy ARM cores.

The ARM-R architecture, specifically the Armv8-R profile, is designed to address the needs of real-time applications, where predictable and deterministic behavior is essential. This profile focuses on delivering high performance, reliability, and efficiency in embedded systems where real-time constraints are critical.
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture (version 5) instruction set.XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE (see more below), with some later models designed as system-on-a-chip (SoC).
