1. In Figure 5.18 (write operation), why is a turn-around cycle not needed between the Address and Data on the AD lines?

2. (see next page)

3. In the PCI protocol each device has its own set of dedicated bus arbitration lines. All of the arbitration lines go to a centralized arbitrator. Why does the PCI protocol not specify a specific arbitration scheme (such as first-come-first-serve)?

2. Draw and explain a timing diagram for a PCI read operation (similar to Figure 5.19). Assume that 2 data transfers occur and that the following occurs during these transfers:

On your diagram clearly indicate:
