We have also designed and validated a queue, the schematic for which is shown in Fig. 19, built by the addition of latches at each C-element block to the Muller pipeline. The queue is used in electronics to regulate and store the flow of information. The asynchronous queue uses the pipeline as a control mechanism to propagate signals between the latches. We use the latch with reset seen in Fig. 12 for this purpose.

Each latch represents some computation that could be completed within each time interval.
