The clocked circuit below is an arbiter. Suppose two devices 1 and 2 can request a resource such as a bus at any instant. The problem is to ensure that only one requester is granted the resource, even if both requests are made simultaneously. The circuit of Figure P12.20 has two request inputs plus a clock and two grant outputs. Explain how the circuit is able to perform its function reliably. Note that the circuit uses edge?triggered flip?flops and that it is immune to metastablilty.
