Virtual memory,

B. Consider a virtual memory environment of size 4KB with page size of 0.25 KB. Physical memory size is 2KB. (This part is independent of question 2.A.) a. Consider the following memory accesses from left to right. Show the final content of the memory page table including the V bit and D bit after performing "all" memory accesses. For unknown entries assume 0 values. 1 2. 3 4 5 6 7 8 OB4 OFO 2A0 2AC 4AC OCC 244 Memory Access No. Virtual Memory Address Physical Memory Address Instruction Executed BOO 2B4 4AC 2F0 lw 4A0 lw lw 2CC Iw 700 Iw SW SW SW b. Consider a TLB structure with two entries and with LRU replacement policy. Draw the TLB include D and U bits. Show the size of each component in number of bits. What is total size in terms of number of bits? Show TLB contents in hexadecimal after "each" memory access. Indicate if a memory access produces a hit or miss for the TLB contents. State the type of each miss
