With the help of the following information, determine the size of the sub-fields (in bits) in the address for direct mapping, associative mapping and set-associative mapping: 512 MB main memory and 2 MB cache memory Address space of the processor is 256 MB The block size is 256 bytes There are 16 blocks in a cache set.

Self doubt about LRU and Direct mapping cache
Can we apply LRU policy to direct mapped cache. according to me it doesn't make any sense as eventually it will be like FIFO only as unique memory addresses are assigned to each cache line. But my doubt / confusion is can we implement LRU on direct mapped caches?
