Cross correlation

A serial input stream can mean a lot of things?

Alice wants to design a circuit which takes two serial inputs sig_x_i and sig_y_i such that the input sig_y_i has randomly delayed versions of 1s seen on the input sig_x_i. The circuit produces an output z_o which is asserted whenever there is an expectation of seeing a 1 on the sig_y_i input. Alice needs your help in designing the circuit.
