【 摘 要 】

CPACM, or Combined Paged And Cached Memory, presents a new way to arrange the memory contained in very large caches. CPACM combines the favorable elements of two previous and more well-known schemes, merging the more conventional cached-memory method with demand paging. This new hybrid scheme consistently performs as well or better than its two predecessors on a wide variety of workloads. This study evaluates CPACM against benchmarks ranging from high end commercial and technical workloads down to very small embedded applications, such as imaging algorithms for printers. 12 Pages
