Consider a CPU that operates with a 3-clock cycle Instruction Fetch, a 2-clock cycle Decode, and a 5-clock cycle Execute. If the system has to complete 10 instructions, what is the total time taken assuming continuous operation?
💡 Hint: Break down time taken per instruction into its phases.
Suppose an instruction fetched has a complex Decode sequence that includes a lookup operation taking longer than usual during execution. How could this affect the Fetch-Decode-Execute cycle's overall timing?
💡 Hint: Think about how delays can propagate in a sequence.
