If a line is selected to be evicted from the L3, then any copies of that line in the L1 or L2 caches of on that chip must also be evicted. Notes: name that means knowledgeWebFor a write-miss, assuming the L1 cache line chosen to evict is dirty, write the old data back to L2 in 10 cycles, read the new data from L2 in 10 cycles to write in the L1 cache line, then write the new data to the L1 cache line. The L1 cache line remains dirty. Total time for a write-miss is 20 cycles. 3.5 name that means logicThe most efficient caching algorithm would be to always discard the information that will not be needed for the longest time in the future.
