Abstract
A priority control device comprises a clock generator for generating a clock signal, a time interval generating unit having a plurality of signal routes and each of the signal routes has a different signal passing time respectively, and a logic control unit coupled to the outputs of the signal routes. The time interval generating unit determines the timing of receiving input signals according to the clock signal. The logic control unit receives the output signals of the signal routes for generating the control signals.
