An analytic method is described for determining the footprint size of a composite mixture of programs that are combined in a fixed proportion; The method can be used in a tool for fast prediction of cache performance under realistic workload environment. Effective design of caches for use in main memory (or disk controllers) must take into account the memory reference (or disk reference) characteristics of what may be considered the typical workload that will be executed very frequently on the computer system. A particular cache design that is good with respect to one type of workload need not be effective when the nature of workload changes. Thus, there exists a need to design a cache that is effective for a combination of workload types.
