Is there any multiplexer(s) present in the implementation of Direct Mapped Cache?If yes, then the Hit latency would be Multiplexer latency + Comparator Latency?

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 ...

The statement " Direct mapped cache, may produce more misses if programs refers to memory words that occupy a same tag value." is true or false ?

I read that if block size increases, then we have fewer blocks so number of conflict misses increases.My doubt is how will the conflict misses increase ? If cache size is...
