7.9 [M] The asynchronous bus protocol in Figure 76 uses a full-handshake, in which the master maintains an asserted signal on Master-ready until it receives Slave-ready, the slave keeps Slave-ready asserted until Master-ready becomes inactive, and so on. Consider an alternative protocol in which each of these signals is a pulse of a fixed width of 4 ns. Devices take action only on the rising edge of the pulse. Using the same parameters as in Problem 7.7, what is the minimum and maximum time to complete one bus transfer
