Designing a processor.. Lecture 15. Virtual Memory. Virtual Memory. Idea 1: . Many Programs sharing DRAM Memory so that context switches can occur. Idea 2: . Allow program to be written without memory constraints – program can exceed the size of the main memory. Virtual Memory. Why Virtual memory?. Allows applications to be bigger than main memory size. Helps with multiple process management. Each process gets its own chunk of memory. Protection of processes against each other. A computer is a machine that is used to store and process data electronically. Computer Definition. Hardware. Pieces . of equipment that make up a computer system. . These . are the parts you can touch (although many parts are contained within the computer’s case). . Chapter 7. Memory Management Techniques. ©Copyright 2008 Umakishore Ramachandran and William D.
