Challenge Problems
Push your limits with advanced challenges
A CPU needs to process 1 million page table entries and uses a TLB, yet registers 0.01% miss rates. If the TLB hit time is 1 nanosecond and miss penalty is 50 nanoseconds, compute the average time for address translation.
💡 Hint: Think about how often the TLB hits versus misses and calculate their respective time contributions.
Discuss the efficiency of managing a page table with 524288 entries versus 256 when considering a hardware implementation in a system that requires frequent context switches.
💡 Hint: Reflect on how larger tables impact context switch time and processing efficiency.
