10.3.1. Instruction Execution Steps

Try these first

1. 1.

   What is the function of a control bus?

   Hint

   Think about how signals travel in a computer system.

2. 2.

   What does ALU stand for?

   Hint

   Focus on the primary operations it performs.

3. 3.

   What is the primary purpose of the ALU in the CPU?

   • To store data temporarily
   • To perform arithmetic and logical operations
   • To manage control signals

   Hint

   Remember its function within CPU operations.

4. 4.

   True or False: The control bus is responsible for data storage.

   • True
   • False

   Hint

   Consider its role in communication, not storage.

5. 5.

   Consider a scenario where a CPU attempts to read data from multiple memory locations at the same time. Explain how control signals would need to be adjusted to prevent contention.

   Hint

   Think about how signals can be queued or prioritized.

6. 6.

   Design a simple flowchart to illustrate the sequence of operations a CPU performs when executing an instruction that involves both reading from memory and writing to a register. Include timing signals.

   Hint

   Break down each step and visualize the sequence.
