Unlike synchronous design style which uses a globally distributed clock signal to indicate moments of stability of the data, asynchronous circuits exchange information using handshakes to explicitly indicate the validity and acceptance of data. Depending on the type of handshaking, data encoding, channel type, and data-validity schemes there are a number of alternative communication protocols. As already discussed in Chap.??, two-phase handshaking is preferred for global on-chip communication since it reduces the number of transitions and avoids the requirement of a spacer between consecutive data symbols. This saves communication time and energy of the system.
