Abstract :
Compact circuits for the implementation of digital CMOS Hamming comparators are presented. One circuit compares the Hamming weight of an n-bit input vector to a fixed threshold, while the other compares the Hamming weights of two independent vectors (of equal or different lengths). Such comparators find applications in median/rank filters, vector quantisers, and digital neural networks.
