Managing the power consumption of ICs is an increasingly difficult challenge, because each new generation of portable device includes expanded features and demands longer battery lives.

The asynchronous logic then calculates the new state of the circuit. For example, the logic cloud could perform an addition or multiplication. Figure 1. Simplified diagram of a synchronous logic stage ...

In contrast to synchronous circuits which operate according to clock timing signals, asynchronous circuits use handshaking between their components (operating virtually autonomously) to perform all ...

Micropipelines. Ivan E. Sutherland: The Turing Award Lecture. Communications of the ACM, Vol. 32, No. 6, pages 720¿738; June 1989. Asynchronous Circuits and Systems. Special issue of Proceedings ...

This includes FIFOs (first in, first out) and switching fabrics, for example. He also noted that the flip-flop is itself a very small asynchronous circuit, and there has been some success in ...

Asynchronous circuits keep the assumption that signals are binary, but remove the assumption that time is discrete. The problems with Synchronous designs being discussed in previous section can be ...

A software tool for automatically converting synchronous circuit designs into asynchronous equivalents is being developed by researchers at the University of Edinburgh. Asynchronous ICs – which do not ...

For example, a study detailing a design support tool set for interface circuits between synchronous and asynchronous modules demonstrated a reduction in overall energy consumption by up to 34% ...
