Consider a computer system $32-$bit addressing scheme, cacheline of $32$B and a direct mapped cache structure with cache size of $4$KB$.$ If the CPU is trying at access addresses using address bus A$[31$:$0],$ then

The number of sets are

$,$ represented by upper address bit A

to lower address bit A

If data from address A$=0$xABCDEFAB is stored in the cache then it is stored in set number $($in decimal$)$

If data from address A$=0$xABCDEFAB is stored in the cache then the address stored in the cache directory is

$($in hex$)$
