Abstract
A method of generating zero detect flag at the output of an adder adding a first vector and a second vector to generate a third vector. A fourth vector is generated from the third vector a carry propagation vector and a carry generation vector. A fifth vector generated using an incremented third vector and an incremented carry propagation vector. A sixth vector generated from the fourth vector and the fifth vector. The bits of the sixth vector bitwise added to obtain the zero detection flag.
