ASYNCHRONOUS DESIGN METHODOLOGIES - AN OVERVIEW

Asynchronous design has been an active area of research since at least the mid 1950's, but has yet to achieve widespread use. We examine the benefits and problems inherent in asynchronous computations, and in s ome of the more notable design methodologies. These include Huffman as ynchronous circuits, burst-mode circuits, micropipelines, template-bas ed and trace theory-based delay-insensitive circuits, signal transitio n graphs, change diagrams, and compilation-based quasi-delay-insensiti ve circuits.
