30.2.1. Fetching Value from Memory Location M

Try these first

1. 1.

   What is the function of the Program Counter (PC)?

   Hint

   Consider what the CPU needs to know to continue processing.

2. 2.

   Name one advantage of having multiple buses in an architecture.

   Hint

   Think about how multiple tasks can be handled simultaneously.

3. 3.

   What does the Program Counter (PC) do?

   • Holds address of next instruction
   • Performs arithmetic operations
   • Stores instruction data

   Hint

   Think about where the CPU looks to fetch the next task.

4. 4.

   True or False: Having multiple buses can lead to the need for more control signals.

   • True
   • False

   Hint

   Consider how parallel processing might affect control efficiency.

5. 5.

   Design a flowchart illustrating the instruction execution process in both single and multiple bus architectures for a specific instruction.

   Hint

   Ensure you include components like PC, MAR, buses, and ALU in the flowchart.

6. 6.

   Evaluate real-world scenarios where single bus architectures might be preferred over multiple bus systems.

   Hint

   Think of scenarios involving smaller applications or microcontrollers.
