4.7. AHB-Lite Bus Timing Diagram

Try these first

1. 1.

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

   Hint

   Think about what the master must do to initiate a transaction.

2. 2.

   What does the HREADY signal indicate?

   Hint

   Consider what needs to happen before data can be transferred.

3. 3.

   What is the sequence of phases in the AHB-Lite bus transfer?

   • Data Phase
   • Address Phase
   • Address Phase
   • Data Phase
   • Control Phase
   • Data Phase

   Hint

   Recall the order of operations in the AHB-Lite protocol.

4. 4.

   True or False: The HREADY signal indicates the success of data transfer.

   • True
   • False

   Hint

   Think about the specific function of HREADY and HRESP.

5. 5.

   Design a timing diagram for an AHB-Lite communication between a master and a slave. Include all control signals and phases.

   Hint

   Draw each phase distinctly; ensure to show waiting states if necessary.

6. 6.

   Evaluate how a delay in the HREADY signal might affect overall system performance in an AHB-Lite architecture.

   Hint

   Consider the effects on timing and synchronization in a broader system context.
