Consider the instructions in the given figure and find the contents of the CPU registers - PC, MAR, MDR, IR, R1 and R2.

To answer your question, I would need specific information from the given figure regarding the CPU registers, including their current values or the instructions affecting them. Since I can't see the figure, I'll guide you through the typical approach to analyze CPU registers based on common scenarios.

1. ### Break Down the Problem

1. Identify the current state of the registers: Program Counter (PC), Memory Address Register (MAR), Memory Data Register (MDR), Instruction Register (IR), and general-purpose registers (R1 and R2).
2. Analyze the instructions provided (if applicable) that may affect these registers.
3. Determine the initial values and any changes that result from executing these instructions.

2. ### Relevant Concepts

• Program Counter (PC): This holds the address of the next instruction to be executed.
• Memory Address Register (MAR): This holds the address in memory from which data will be fetched or to which data will be written.
• Memory Data Register (MDR): This holds the data being transferred to or from memory.
• Instruction Register (IR): This holds the current instruction that is being executed.
• General-purpose registers (R1, R2): These registers hold temporary data and may store execution results.

3. ### Analysis and Detail

• To find the contents of each register, we need to track the flow of instructions and their effects on the CPU registers.
• If instructions are provided in the figure, follow the steps they indicate to update each register accordingly. For example:
  • If the PC increments, calculate its new value.
  • If the MAR is loaded from the PC, note that value.
  • After data is fetched or stored, update the MDR accordingly.
  • Decode the instruction in the IR and determine its effect on R1 and R2.

4. ### Verify and Summarize

• Once each register's contents are determined, summarize their final states.
• Verify calculations or values by checking against CPU instruction sets or the sequence of operations given in the figure.

Final Answer

Please provide the specific content or sequence of operations associated with the registers mentioned, and I can then help you find the values for PC, MAR, MDR, IR, R1, and R2 accurately based on that information.
