6.2.3. Design Control Signals

Try these first

1. 1.

   What are control signals in the context of a CPU?

   Hint

   Think about what directs the CPU's actions.

2. 2.

   Define micro instructions.

   Hint

   What do we call the instructions that are broken down from macro instructions?

3. 3.

   What role do control signals play in a CPU?

   • They execute instructions
   • They manage component actions
   • They store data

   Hint

   Think about who tells the CPU what to do.

4. 4.

   True or False: More buses in an architecture lead to reduced execution times.

   • True
   • False

   Hint

   Consider how data travels through a CPU.

5. 5.

   Design a flowchart that outlines the control signal generation for a simple instruction that multiplies two numbers.

   Hint

   Break it down into key operations just like in our earlier discussions.

6. 6.

   Evaluate the differences in instruction execution timing between a single bus architecture and a three bus architecture.

   Hint

   Think about how many processes can happen at once in each system.
