Q44

A system has a Translation Lookaside Buffer (TLB) that has a reach of $1$ MB. TLB reach is defined as the total amount of physical memory that can be accessed through the TLB entries. The paging system uses pages of size $4$ KB. The virtual address space is $64$ GB and physical address space is $1$ GB. If each TLB entry stores a $4$-bit process id, page number, frame number, and a $2$-bit control field, then the size of the TLB (in bytes) is $\_\_\_\_\_\_$. (answer in integer) Note: $1 \mathrm{K}=2^{10}, 1 \mathrm{M}=2^{20}, 1 \mathrm{G}=2^{30}$
