Unformatted text preview: perform its own timing functions whenever it has useful work to perform, are clear in theory but there are few demonstrations that the benefits can be realized in practice with circuits of sufficient complexity to be commercially interesting. The AMULET research is aimed directly at adding to the body of convincing demonstrations of the merits of asynchronous technology. An obstacle to the widespread adoption of self-timed design styles is the knowledge-base of the existing design community. Most 1C designers have been trained to have a strong aversion to asynchronous circuits because of the difficulties that were experienced by the designers of some early asynchronous computers. These difficulties resulted from an undisciplined approach to self-timed design, and modern developments offer asynchronous design frameworks which overcome most of the problems inherent in what is, admittedly, a more anarchic approach to logic design than that offered within the clocked framework. Example and exercises 397 The next few years will tell whether or not AMULET and similar developments around the world can demonstrate the sort of advantages that will cause designers to throw away most of their past education and learn a new way to perform their duties. AMULET Support AMULET 1 was developed using European Community funding within the Open Microprocessor systems Initiative - Microprocessor Architecture Project (OMIMAP). AMULET2 was developed within the Open Microprocessor systems Initiative - Deeply Embedded ARM (OMI-DE/ARM) project. The development of AMULETS and DRACO was supported primarily within the European Union funded OMI-DE2 and OMI-ATOM projects. Aspects of the work have benefited from support from the UK government through the Engineering and Physical Sciences Research Council (EPSRC) in the form of a PhD studentships and the tools development funded under ROPA grant GR/K61913. The work also received support in various forms from ARM Limited, GEC Plessey Semiconductors (now part of MITEL) an...
