19.56 MOV (scalar)

Move vector element to scalar.

This instruction is an alias of DUP (element).

The equivalent instruction is DUP Vd, Vn.T[index].

Syntax

MOV Vd, Vn.T[index]

Where:

V
Is the destination width specifier, and can be one of the values shown in Usage.
d
Is the number of the SIMD and FP destination register.
Vn
Is the name of the SIMD and FP source register.
T
Is the element width specifier, and can be one of the values shown in Usage.
index
Is the element index, in the range shown in Usage.

Usage

Move vector element to scalar. This instruction duplicates the specified vector element in the SIMD and FP source register into a scalar, and writes the result to the SIMD and FP destination 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.

The following table shows the valid specifier combinations:
