One method of increasing performance on mainframe and minicomputers has been to implement a cache memory as a small, high speed memory array between the processor and slower main memory. As the demand for desk- top processing power increases, the addition of a cache memory to microprocessor-based workstations, such as the Personal Computer AT/ 370, becomes attractive. Traditionally, software simulation has been employed to quantify the performance gain provided by using a cache memory. One alternative that retains the versatility of a software simulation model, yet provides a more accurate measurement of the increase in system throughput, is a general-purpose Hardware Cache Simulator. A Hardware Cache Simulator can simulate many different sizes of cache memory, varying in both width and number of entries.
