5.6. Synchronization and Timing Control

Try these first

1. 1.

   What is the role of the HREADY signal?

   Hint

   Think about how the controller knows when to proceed.

2. 2.

   Why are wait states important?

   Hint

   Consider what happens if multiple operations happen simultaneously.

3. 3.

   What does the HREADY signal indicate?

   • Memory is busy
   • Memory is ready
   • Data is corrupted

   Hint

   Recall the purpose of the HREADY signal in data transfers.

4. 4.

   True or False: Wait states can help manage busy SRAM effectively.

   • True
   • False

   Hint

   Consider when the memory might be busy.

5. 5.

   Design a small memory control system that uses the concepts of wait states and HREADY signals. Describe how you would implement these in your design.

   Hint

   Think about how to synchronize operations with a busy resource.

6. 6.

   Evaluate the potential impact on performance in a system that does not manage wait states effectively. What errors could arise from such mismanagement?

   Hint

   Consider the interactions between multiple processes relying on the same memory access.
