20.120 MOV (vector, to general)

Move vector element to general-purpose register.

This instruction is an alias of UMOV.

The equivalent instruction is UMOV Wd, Vn.S[index].

Syntax

MOV Wd, Vn.S[index] ; 32-bit

MOV Xd, Vn.D[index] ; 64-bit

Where:

Wd
Is the 32-bit name of the general-purpose destination register.
index

The value depends on the instruction variant:

32-bit
Is the element index.
64-bit
Is the element index and can be either 0 or 1.
Xd
Is the 64-bit name of the general-purpose destination register.
Vn
Is the name of the SIMD and FP source register.

Usage

Move vector element to general-purpose register. This instruction reads the unsigned integer from the source SIMD and FP register, zero-extends it to form a 32-bit or 64-bit value, and writes the result to the destination general-purpose register.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
