High speed self-timed pipelined datapath for square rooting

The authors describe a new highperformance self-timed circuit for asynchron ous square rooting. The new architecture is based on a modified nonrestorin g algorithm. An asynchronous pipelined cellular array without auxiliary sys tem for the identification of exceptions will be demonstrated. The self-tim ing approach allows the whole performance to be greatly improved with respe ct to synchronous implementation, causing acceptable area overheads.
