Question 1

What is the role of an opcode in an instruction?

  • Specifies the data location
  • Identifies the operation to be performed
  • Stores the result of execution

💡 Hint: Focus on what the instruction needs to tell the CPU.

Question 2

True or False: The result operand in an instruction is where the operation's input is located.

  • True
  • False

💡 Hint: Remind yourself of the roles of source and result operands.

Challenge Problems

Push your limits with challenges.

Question 1

Design an instruction format that contains an opcode for addition, two source operands, and a result operand. What would the minimum bit requirements be if you want to support 16 different addition variants?

💡 Hint: Calculate bits needed for opcodes versus operand storage.

Question 2

If a CPU has both 2-address and 3-address instruction formats, compare the potential speed and efficiency of execution of both. Which one would you prefer for performance-intensive applications and why?

💡 Hint: Consider trade-offs between instruction length and complexity.
