limsk.ece.gatech.edu• Synchronous sequential system • Behaviour depends on the inputs and outputs at discrete instants of time. • Flip-flops, registers, and latches that are enabled/controlled with a signal derived from clock form a synchronous sequential system. • Asynchronous sequential system • Behaviour depends on inputs at any instant of time.
Asynchronous Sequential Circuits - Stanford University
web.stanford.educussed in Section 14.2. In both cases we compute a next state based on current state and input. What’s different is the dynamics of how the current state is updated with the next state. Without a clocked state register, the state of an asynchronous sequential circuit may change at any time (asynchronously).
