no i think its not possible also. If the block is not there in the cache how
you will find the address?

initially by using findBlock it gets the block and then invalidated all
the
blocks, my point is when a cpu requests, it will check the tag and valid
bits for hit else its a miss. yeah it's not possible in set associative
caches but what about direct mapped?

I think, I don't understand what you are trying to do. Anyways, in a direct
mapped cache, since there is only one block per set, you can always add a
function that returns you that one block.
The address being accessed can give you the set. That set has only one
block (since it is direct mapped cache), so we do not need the actual
address of the block stored in the cache.
