15 Aug Check whether the entry is in the TLB

In this system, when a virtual address is requested:

1. Check whether the entry is in the TLB. – If yes, directly return the frame number; – If no, continue step 2.
2. Get the page table by segment number.
3. Get the frame number by page number.
4. Replace the TLB entry with the new record.
5. Retrieve the data.

Givens are some incomplete source files. You need to complete:

tlb.cpp:

int TLB::get_frame(VirtualAddress vaddr)

void TLB::lru_replace(VirtualAddress vaddr, unsigned int frame)

main.cpp:

int address_translate(VirtualAddress vaddr)

You can find the instructions and hints in the comments of the source file.

Your final output should be exactly the same as attached png file:
