Assume that a hypothetical system in which program execution gives 200 stall cycles per instruction on an average. There are 260 and 120 misses in L1 (Level1) and L2 (Level­2) cache out of total 1000 CPU references. If L2 to memory miss penalty is twice the hit time. What are hit time of L2 and “L2 to memory miss penalty”  values  respectively  (in  cycles)?  [Given  2.5  memory  reference  per instruction]
a. 300, 600

b. 400, 800

c.  160, 320

d. 160, 340
