Name

usubBorrow — subtract unsigned integers and generate borrow

Declaration

genUType usubBorrow( genUType x,
genUType y,
out genUType borrow);

Parameters

x

Specifies the first vector to be used in the subtraction operation.

y

Specifies the second vector to be used in the subtraction operation.

borrow

Specifies the variable to receive the borrow output of the difference.

Description

usubBorrow subtracts two 32-bit unsigned integer variables (scalars or vectors) and generates a 32-bit unsigned integer result, along with a borrow output. The result is the difference of x and y if non-negative, or 232 plus that difference otherwise. The value borrow is set to 0 if xy and to 1 otherwise.
