1. Design a parallel arbitration system using three levels of parallel arbiter parts and determine the arbitration time of the system.
2. Suppose a rotating daisy chain priority circuit has the following signals:
And contains on J-K flip-flop whose output, BMAST (bus master), indicates that the master is the current bus master. Draw a state table showing the eight different states of the circuit. Derive the Boolean expressions for the flip-flop inputs, and for BROUT. (See Nelson and Refai (1984) for solution.)
