Two-input sorter animation
A two-input sorter consists of 2 inputs (X and Y) and 2 outputs, which are simultaneously computed. Those outputs are the logic operations a) X AND Y and b) X OR Y. To achieve the simultaneous computation of AND and OR, each input signal is doubled -- split into two cascades by a "fanout" arrangement. Since these cascades operate on a surface in two dimensions, the signals must also pass through each other using the "crossover" construction in the center of the device. (Click mouse to start X input.)
