CPACM: A New Embedded Memory Architecture Proposal

Keltcher, Paul; Richardson, Stephen


Keyword(s): eDRAM; embedded DRAM; demand paging; cache; CMP; multiprocessor; CPACM

Abstract: 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.
