Question 1

What is the primary function of the Instruction Register?

  • Holds the current instruction
  • Stores data temporarily
  • Increments the program counter

💡 Hint: What part of the CPU directly deals with executing commands?

Question 2

Control signals are used to coordinate CPU operations. True or False?

  • True
  • False

💡 Hint: Think about what ensures orderly processing of multiple tasks.

Challenge Problems

Push your limits with challenges.

Question 1

Design a detailed overview of how the CPU handles fetching the instruction to execute 'SUB R2, R3', and explain the role of each register involved in the process.

💡 Hint: Break down the steps one by one focusing on what happens at each stage.

Question 2

Evaluate the efficiency impacts of using registers over memory access in CPU operations observable in 'LOAD R1, M' vs 'ADD R2, R3'. How does this affect execution time?

💡 Hint: Consider how often each operation accesses memory to weigh the execution time differences.
