Objectives: To study how a cache system works. After completing this experiment, you should know the organization of different cache systems and how a cache system operates with its cache management system. Software: The CacheSim simulation program Introduction: A cache is a high$-$speed memory system between the microprocessor and the DRAM memory system. A buffer allows a computer system to function more efficiently with DRAM at lower access speeds. It can improve the overall performance of a memory system when data are accessed more than once.
