Consider a memory system with the following parameters:

$-$ Translation Lookaside Buffer has $256$ data blocks and is $2-$way set associative.

$-$ Virtual addresses are $64-$bits and physical addresses are $32$ bits.

$-4$ KB page size

Below is the TLB diagram. How many bits are in the fields F$,$ G$,$ H$,$ I?

TLB

Answer: $\backslash (\backslash$mathrm$\{$F$\}=45\backslash )($tag$),\backslash (\backslash$mathrm$\{$G$\}=7\backslash )($Index$),\backslash (\backslash$mathrm$\{$H$\}=12\backslash )($page offset$),\backslash (\backslash$mathrm$\{$I$\}=20\backslash )($physical page number$)$
