AESE
AES single round encryption
AES single round encryption.
For more information about the constrained unpredictable behavior of this instruction, see Architectural Constraints on UNPREDICTABLE behaviors.
If CPSR.DIT is 1:
The execution time of this instruction is independent of:The values of the data supplied in any of its registers.The values of the NZCV flags.
The response of this instruction to asynchronous exceptions does not vary based on:The values of the data supplied in any of its registers.The values of the NZCV flags.
It has encodings from the following instruction sets:
A32 (
A1
)
and
