mov

Move Element to Element

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

Moves a vector element to another vector element (Alias for INS).

Pseudocode Operation

src_index ← decode_src_index_from_imm5(imm5);
dst_index ← decode_dst_index_from_imm5(imm5);
element_size ← decode_element_size(imm5);
Vd.<element_size>[dst_index] ← Vn.<element_size>[src_index];

Example

MOV v0.4s.Ts[index1], v1.4s.Ts[index2]

Description

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.
