SOLUTION

• A complete transfer operation over the BUS, involving the address and a burst of data is called a Transaction.
• Consider a bus transaction in which the processor reads four 32-bit words from the memory.
• In this case, the initiator is the processor and the target is the memory.
• A complete transfer operation on the bus, involving an address and a burst of data, is called a transaction.
• Individual word transfers within a transaction are called phases.
• A clock signal provides the timing reference used to coordinate different phases of a transaction.
