Fetch–Decode–Execute Quiz

A simple CPU fetches, decodes, and executes three instructions stored in memory: LOAD R1,100; ADD R1, R2; STORE R1,200.

1 LOAD R1, 100   # Fetch value from memory address 100 into register R1
2 ADD R1, R2     # Add contents of R2 to R1
3 STORE R1, 200  # Store R1's result into memory address 200
