Q47

Consider a system with a two-level paging scheme in which a regular memory access takes $150$ $nanoseconds$, and servicing a page fault takes $8$ $milliseconds$. An average instruction takes $100$ nanoseconds of CPU time, and two memory accesses. The TLB hit ratio is $90$%, and the page fault rate is one in every $10,000$ instructions. What is the effective average instruction execution time?
