Digital Pulse Logic - A New Paradigm for the Hardware Realization of Combinational and Sequential Digital Logic

In this paper, we describe a pulse stream neural network approach for realising combinational and sequential logical functions, to be henceforth referred to as Digital Pulse Logic. The elemental unit or neuron is based on a modified Phase Locked Loop, using which we design digital gates and sequential blocks. Such implementations offer very wide noise margins and are thus more robust in comparison with conventional implementations. We discuss both open loop and closed loop implementations.
