Question 1

What is the role of the Program Counter (PC)?

To hold the current instruction
To keep track of the next instruction's address
To manage memory data

💡 Hint: Think about its job of keeping things in order.

Question 2

True or False: Control signals determine when data can be retrieved from memory.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

How would the execution process change if the CPU did not have a dedicated Memory Address Register (MAR)? Explain the implications.

💡 Hint: Consider how the CPU currently quickly accesses addresses and what impact misaddressing could have.

Challenge 2 Hard

Given an instruction cycle, simulate the increment of the PC and the flow of data from the MDR to the IR. Describe the signals that guide this process.

💡 Hint: Trace the exact steps from the start to the end of the instruction cycle and keep an eye on the signals.
