4.4. AHB-Lite Bus Protocol

Try these first

1. 1.

   What is the purpose of the Address Phase in the AHB-Lite Bus Protocol?

   Hint

   Think about what must happen before data can be transferred.

2. 2.

   Define what a burst transfer is.

   Hint

   Consider how efficiency can be improved during data transfers.

3. 3.

   What is the first step of a transaction in the AHB-Lite protocol?

   • Data Phase
   • Address Phase
   • Response Phase

   Hint

   Think about what happens before data can be sent.

4. 4.

   True or False: The AHB-Lite protocol supports multiple masters.

   • True
   • False

   Hint

   Recall the main characteristic that differentiates AHB-Lite from the full AHB.

5. 5.

   Given a scenario where a master device needs to send 10 data items to a peripheral in the AHB-Lite protocol, explain how burst transfers would function in this situation.

   Hint

   Consider how reducing the overhead of repeated addressing can speed up the process.

6. 6.

   If a slave device is busy and cannot respond, but an AHB-Lite transaction needs to continue, define how handshake signals can assist in managing this situation.

   Hint

   Think about the roles of signaling in managing traffic on the data bus.
