usubBorrow — subtract unsigned integers and generate borrow
| ||genUType x,|
|out genUType borrow |
Specifies the first vector to be used in the subtraction operation.
Specifies the second vector to be used in the subtraction operation.
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
y if non-negative, or plus that difference otherwise. The value
borrow is set to 0 if
y and to 1 otherwise.
