MOV (element)

Move vector element to another vector element

This instruction copies the vector element of the source SIMD&FP register to the specified vector element of the destination SIMD&FP register.

This instruction can insert data into individual elements within a SIMD&FP register without clearing the remaining bits to zero.

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.

Encoding: Advanced SIMD

MOV <Vd>.<Ts>[<index1>], <Vn>.<Ts>[<index2>]

Equivalent to: INS <Vd>.<Ts>[<index1>], <Vn>.<Ts>[<index2>]

Explanations

<Vd>: Is the name of the SIMD&FP destination register, encoded in the "Rd" field.
<Ts>: <index1>: <Vn>: Is the name of the SIMD&FP source register, encoded in the "Rn" field.
<index2>:

Operational Notes

If PSTATE.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.
