Since the processors have more than one level f memory, how is the 2nd level of Cache accessed.
Access both the first level of Cache and 2nd level are Cache are accessed at the same time. If it is a hit in 1st level then it may stop searching in the 2nd level. Disadvantage is higher power dissipation
Second level of cache is accessed only after the miss of first level. So the time of getting the data is more and the processor performance may drastically decrease if the first level of cache is a bit larger
