Abstract
An asynchronous circuit including an asynchronous pipeline including two or more stages, each stage having: a buffering circuit for temporarily storing data to be transferred from one stage to the next based on a handshake protocol, the buffering circuit including a non-volatile memory; and a data presence detection circuit adapted to generate a data presence detection value indicating whether or not data is stored by the buffering circuit; and a control circuit adapted to perform a data back-up operation by independently controlling each buffering circuit to back-up the data it stores to its non-volatile memory based on the corresponding data presence detection value.
