Project Overview:
The project of implementing a Virtual Memory Management Simulation proved to be a very difficult but interesting task. The idea was to implement the typical virtual memory hierarchy and simulate how an MMU would handle a series of instructions delivered to it.
To do this we created a variety of data structures that acted as a TLB, a DRAM, and a Page Table. Each demonstrating the events and states created from things like hits, misses, and even overall page faults. All of this information being displayed in the below statistics. But we also had to implement the correct outcomes of each event, including maintaining timings and creating an LRU algorithm for TLB entry replacement and page-replacement.
