Given the hit ratio of level-1 cache is 0.1 and the access time is 1, the hit ratio of level-2 cache is 0.2 and the access time is 10, the hit ratio of level-3 cache is 0.3 and the access time is 100, and the hit ratio of the main memory is 0.4 and the access time of the main memory is 1000, what are the CETA, NETA if 3-level cache is applied and the ETA if no cache is applied?
