Data-controlled delays in the asynchronous design

Asynchronous design technique has an approach of using padding delays to produce signals of transient process completion. In order to increase the efficiency of this approach, we suggest to use data-controlled incorporated delays in the cases when the variations of transient process durations are determined by the sets of input signal values. The control over the value of an incorporated delay is illustrated by an example of asynchronous adder design. The results of PSPICE simulation confirm the efficiency of this approach
