@manisha11 tag bits will obviously be needed and for block we will take as byte addressable and so 64 bits  = 64/8 = 8 bytes = 2^3 , so min value of x = 16+3 = 19

oh yes 64/8 thanks

I am also getting 19 as answer Any one please Verifiy….

Answer 1

To get minimun value of X , you should consider that it is block addressable where block size should be 64 bits.

So minimun number of bits will be only for tag bits.

So x=16.

does this mean here one word is of 64bits ?

Actually somewhere it is Block addressable while somewhere it is word addressable.Just different terminology.

Yes
