Question 1

What is the primary function of a hardwired control unit?

  • Generate control signals via software
  • Generate control signals through fixed logic
  • Interpret instructions via microprogramming

💡 Hint: Think about the fixed nature of hardwired vs. soft designs.

Question 2

True or False: Hardwired control units are easy to modify.

  • True
  • False

💡 Hint: Consider what happens if we want to change something physically.

Challenge Problems

Push your limits with challenges.

Question 1

Design a simple FSM for a CU that handles a sequence of three operations: LOAD, ADD, and STORE. Define states, transitions, and the control signals for each.

💡 Hint: Start by defining each operation as a separate state and think about how they would follow each other.

Question 2

Compare and contrast the design complexities of a hardwired CU versus a microprogrammed CU. What type of flexibility does each offer?

💡 Hint: Consider how each design choice affects overall performance and adaptability.
