12.6 VABD and VABDL

Vector Absolute Difference.

Syntax

VABD{cond}.datatype {Qd}, Qn, Qm

VABD{cond}.datatype {Dd}, Dn, Dm

VABDL{cond}.datatype Qd, Dn, Dm

where:

cond

is an optional condition code.

datatype

must be one of:

  • S8, S16, S32, U8, U16, or U32 for VABDL.

  • S8, S16, S32, U8, U16, U32 or F32 for VABD.

Qd, Qn, Qm

are the destination vector, the first operand vector, and the second operand vector, for a quadword operation.

Dd, Dn, Dm

are the destination vector, the first operand vector, and the second operand vector, for a doubleword operation.

Qd, Dn, Dm

are the destination vector, the first operand vector, and the second operand vector, for a long operation.

Operation

VABD subtracts the elements of one vector from the corresponding elements of another vector, and places the absolute values of the results into the elements of the destination vector.

VABDL is the long version of the VABD instruction.
