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.

This is an alias of INS (element). This means:

01101110000imm50imm41RnRd

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

is equivalent to

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

and is always the preferred disassembly.

Assembler Symbols

<Vd>

Is the name of the SIMD&FP destination register, encoded in the "Rd" field.

<Ts>

Is an element size specifier, encoded in imm5:

imm5<Ts>
x0000RESERVED
xxxx1B
xxx10H
xx100S
x1000D
<Ts> Is an element size specifier, encoded in imm5:
imm5<Ts>
x0000RESERVED
xxxx1B
xxx10H
xx100S
x1000D
<index1>

Is the destination element index encoded in imm5:

imm5<index1>
x0000RESERVED
xxxx1imm5<4:1>
xxx10imm5<4:2>
xx100imm5<4:3>
x1000imm5<4>
<index1> Is the destination element index encoded in imm5:
imm5<index1>
x0000RESERVED
xxxx1imm5<4:1>
xxx10imm5<4:2>
xx100imm5<4:3>
x1000imm5<4>
<Vn>

Is the name of the SIMD&FP source register, encoded in the "Rn" field.

<index2>

Is the source element index encoded in imm5:imm4:

imm5<index2>
x0000RESERVED
xxxx1imm4<3:0>
xxx10imm4<3:1>
xx100imm4<3:2>
x1000imm4<3>
Unspecified bits in "imm4" are ignored but should be set to zero by an assembler.
<index2> Is the source element index encoded in imm5:imm4:
imm5<index2>
x0000RESERVED
xxxx1imm4<3:0>
xxx10imm4<3:1>
xx100imm4<3:2>
x1000imm4<3>
Unspecified bits in "imm4" are ignored but should be set to zero by an assembler.
