Overview of ARM v8 Processors: Architecture and Technology

​ Overview of ARMv8 Architecture The ARMv8 architecture includes 32-bit and 64-bit execution states, introducing the ability to execute with 64-bit wide registers while providing backward compatibility mechanisms to allow existing ARMv7 software to run. • AArch64: The 64-bit execution state in ARMv8. • AArch32: The 32-bit execution state in ARMv8, which is nearly identical … Read more
