ARMv8, ARMv9

• https://en.wikipedia.org/wiki/ARM_architecture_family
• ARMv8 is an ARM instruction set architecture announced in 2011. It brought a large number of fundamental changes to the instruction set, including the introduction of 64-bit operating capabilities. ARMv8 architecture uses two execution states, AArch32 and AArch64. As the names imply, one is for running 32-bit code and one for 64-bit.
• After ARMv8, which was introduced in 2011, ARM introduced ARMv9 architecture.
• According to ARM, some of the major new features of the ARMv9-A architecture include Realm Management Extension (RME) and Embedded Trace Extension (ETE) and Trace Buffer Extension (TRBE).
• Apple M1 chip or M2 chip is based on ARMv8.5-A instruction set architecture.
