12.96 VQSUB

Vector Saturating Subtract.

Syntax

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

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

where:

cond

is an optional condition code.

datatype

must be one of S8, S16, S32, S64, U8, U16, U32, or U64.

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.

Operation

VQSUB subtracts the elements of one vector from the corresponding elements of another vector, and places the results in the destination vector.

The sticky QC flag (FPSCR bit[27]) is set if saturation occurs.
