represents a fundamental change to the ARM architecture. It adds an optional 64-bit
Execution state, named "AArch64", and the associated new "A64" instruction set, in addition to a 32-bit Execution state, "AArch32", supporting the 32-bit "A32" (original 32-bit Arm) and "T32" (Thumb/Thumb-2)
1350:
With the introduction of optional AArch64 support in the Armv8-R profile, the real-time capabilities have been further enhanced. The Cortex-R82 is the first processor to implement this extended support, bringing several new features and improvements to the real-time domain.
783:
An ARMv8-A processor can support one or both of AArch32 and AArch64; it may support AArch32 and AArch64 at lower
Exception levels and only AArch64 at higher Exception levels. For example, the ARM Cortex-A32 supports only AArch32, the
