CS301: Computer Architecture

Watch this lecture, which addresses the subject of virtual memory. This topic pertains to the relationship of main memory and secondary memory and has similarities and differences to the relationship of cache and main memory. Differences arise due to the speed of the various memories and their capacities. This lecture discusses virtual memory, mapping from virtual memory addresses to physical addresses in main and paging techniques used with the main memory. The lecture discusses the use of page tables in translating virtual addresses to physical addresses. Issues that arise with page tables include structure, location, and large size.
