ARM Architecture Reference Manual ARMv7-A and ARMv7-R edition

Pseudocode Definition
I.7.28 MemorySystemArchitecture()
This function returns a value indicating which memory system architecture is in use on the system.
enumeration MemArch {MemArch_VMSA, MemArch_PMSA};
MemArch MemorySystemArchitecture()
I.7.29 ProcessorID()
This function returns an integer that uniquely identifies the executing processor in the system.
integer ProcessorID()
I.7.30 RemapRegsHaveResetValues()
This function returns TRUE if the remap registers PRRR and NMRR have their IMPLEMENTATION DEFINED
reset values, and FALSE otherwise.
boolean RemapRegsHaveResetValues()
I.7.31 SwitchToJazelleExecution()
This procedure passes control of execution to Jazelle hardware (for a BXJ instruction).
I.7.32 ThisInstr()
This function returns the currently-executing instruction. It is only used on 32-bit instruction encodings at
present.
bits(32) ThisInstr()
I.7.33 UnalignedSupport()
This function returns TRUE if the processor currently provides support for unaligned memory accesses, or
FALSE otherwise. This is always TRUE in ARMv7, controllable by the SCTLR.U bit in ARMv6, and
always FALSE before ARMv6.
boolean UnalignedSupport()
