Abstract: To solve the time constraint of scheduling algorithm in the feedback-based two-stage switch architecture (FTSA), a new scheme called pulsating feedback-based two-stage switch architecture (PFTSA) is proposed, which transmits the required information back to the input port in a way of pulsating. The accurate data of target buffers can be obtained by the scheduling algorithm with a preprocessing scheme, so as to avoiding the cell conflicting and disordering. As compared to the existing schemes, PFTSA can not only simplify the switch architecture and procedure, but also improve the delay performance.
