A method for designing delay-insensitive circuits is presented based on a simple formalism. The communication behavior of a circuit with its environment is specified by a regular expression-like program. Based on formal manipulations this program is then transformed into a delay-insensitive network of basic elements realizing the specified circuit. The(More)
One of the most frequently used primitives in asyn-chronous control circuits is the C-element. The three most popular CMOS implementations of the C-element are compared with respect to energy-eciency, delay, and area, with an emphasis on energy. The three implementations have been introduced by Sutherland, Mar-tin, and Van Berkel. We show that in a typical(More)
This paper presents a method for designing a special type of asynchronous circuits, called Gasp circuits, and illustrates the method by a novel design of a low-latency, high-throughput FIFO, called a Square FIFO. The design method includes a graphical notation that permits the specification not only of circuit topology but also of the time separation(More)

Proximity Communication (PxIO) is an interchip communication technology that offers important advantages over conventional chip-to-chip I/O, including high channel density and low power. Proximity Communication places chips face-to-face, within a few microns of one another [1]. Capacitive coupling between top-level metal I/O structures permits efficient(More)
