usubBorrow — subtract unsigned integers and generate borrow
genUType usubBorrow( | genUType x, |
| genUType y, | |
out genUType borrow); |
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.
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 plus that difference otherwise. The value borrow is set to 0 if x ≥ y and to 1 otherwise.
