Now … WebHamming weight of a binary vector with a constant, as well as comparing the Hamming weights of two input vectors, are proposed. It is shown that the proposed comparators are faster and simpler, both in asymptotic sense and for moderate vector lengths, compared with the best available fully digital designs.
