Question 1

What happens to the Program Counter after an instruction is executed?

  • It resets to zero
  • It increments to the next instruction
  • It remains unchanged

💡 Hint: Consider what it means to execute a sequence.

Question 2

True or False: The control signals are unnecessary for the increment operation.

  • True
  • False

💡 Hint: Think about the role of control signals in any operation.

Challenge Problems

Push your limits with challenges.

Question 1

In a hypothetical scenario, the PC is not incrementing correctly due to a faulty control signal. Describe the potential impacts this defect could have on program execution.

💡 Hint: Consider what happens during a typical fetch-decode-execute cycle.

Question 2

Given a simplistic instruction set where every instruction requires only one clock cycle to complete, calculate how many instructions can be successfully executed in a second if the PC increments every cycle correctly. What factors could reduce this rate?

💡 Hint: Think about how clocks regulate CPU operations.
