Problem 2: Virtual Memory Simulation
Goal: To simulate and evaluate a virtual memory system, and experiment with different page replacement algorithms. You will need a threads package, e.g. pThreads thread package.
Assume that you have a 16-bit address space, 16 KB of main memory, and 2 KB page size. Virtual memory simulation consists of three components: virtual address generation component, address translation component, and statistics reporting component.
Implement each component by a separate thread.
The virtual address generation component generates a sequence of 16-bit virtual addresses and writes them in an integer buffer inBuffer of size 10. Write a function getNextVirtualAddress( ) for generating virtual addresses. This function may generate virtual addresses at random or based on a trace obtained from some source.
The address translation component implements virtual address to physical address translation using a page replacement algorithm. This component reads the next virtual address from inBuffer and translates that address to a physical address. It prints the virtual address and corresponding physical address in a file. It also increments an integer variable (numberOfPageFaults) on every page fault. Use appropriate bit operations (<<, >>, ~, |, &, etc.) to implement this address translation. Implement a separate version of this component for every page replacement algorithm you want to experiment with.
The statistics reporting component prints the total number of page faults
(numberOfPageFaults) at the end.
