vec_mladd

Purpose

Returns a vector containing the results of performing a saturated multiply-low-and-add operation on each corresponding set of elements of three given vectors.

Syntax

d=vec_mladd(a, b, c)

Result and argument types

The following table describes the types of the returned value and the function arguments.

Result value

The value of each element of the result is the value of the least significant 16 bits of the product of the values of the corresponding elements of a and b, added to the value of the corresponding element of c.

The addition is performed using modular arithmetic.
