31.1.4. Control Signals in Bus Architectures

Try these first

1. 1.

   What is the function of the Memory Data Register (MDR)?

   Hint

   Think about where data is stored during transfers.

2. 2.

   Define a single bus architecture.

   Hint

   Consider how many channels are used in a bus system.

3. 3.

   What is the role of control signals in bus architectures?

   • To manage data transfer
   • To store data
   • To execute programs

   Hint

   Refer to the function of control signals.

4. 4.

   True or False: A single bus architecture allows for simultaneous data transfers.

   • True
   • False

   Hint

   Consider how the architecture operates.

5. 5.

   Given a scenario where a three-bus architecture is processing operations and a data transfer needs to be made from MDR to R1, simulate the sequence of control signals required for this operation.

   Hint

   Outline specific steps sequentially to identify required signals.

6. 6.

   Consider a performance issue arising from control signal management in a three-bus architecture. Propose ways to mitigate these issues while maintaining efficiency.

   Hint

   Think about technology solutions that can optimize signal management.
