Abstract :
A synthesis procedure for designing asynchronous controllers from burst-mode specifications, a class of specifications allowing multiple-input-change fundamental mode operation, is described. This implementation of burst-mode state machines uses standard combinational logic, generates low-latency outputs and guarantees freedom from hazards at the gate level. It requires no locally synthesized clock and no storage elements. In addition, primary outputs as well as additional state variables are used as feedback variables. The state assignment technique is based on the construction of a three-dimensional next-state table
