ABSTRACT:
An iterative logic circuit for iteratively performing a logic function includes a two-input logic gate and a D-type flip-flop. The flip-flop receives and time-delays the output signal from the logic gate to provide a feedback signal as one of the input signals to the logic gate. By sequentially processing the feedback signal together with a serial input data signal, the logic gate iteratively performs an associative logic function (e.g. EXCLUSIVE-OR) upon the serial input data signal, thereby performing a parallel logic function by executing a serial logic operation.
