SYSTEM AND METHOD OF REDUCING TRAFFIC AMONG MULTI-CORES USED TO MEET CACHE COHERENCE

摘要

PURPOSE: A system capable of reducing communication rates between multi-cores and method thereof are provided to minimize power consumption by adding sharing information to a conversion reference buffer within a core. CONSTITUTION: A conversion reference buffer(140) includes sharing information between virtual and physical page cores. An OS(Operating System) manages a page table including the sharing information and relations between the virtual and physical page. The sharing information displays a non-sharing state when the number of the core which accesses to the page table is one. The sharing information displays a sharing state when the cores which access to the page table are two. The sharing information includes the identification all cores which access to the page table.
