DATA REPLACEMENT METHOD IN SYSTEM CACHE AND MULTI-CORE COMMUNICATION PROCESSOR

摘要

A data replacement method in a system cache includes: the system cache acquires the access statistic value corresponding to each packet header data in the system cache, wherein the access statistic value corresponding to the packet header data indicates the difference obtained when the times for which the packet header data have already been accessed by a Central Processing Unit (CPU) is subtracted from the predetermined access times of the packet header data; the system cache acquires the packet header data to be transferred according to the access statistic value corresponding to each packet header data; the system cache transfers the packet header data to be transferred to an external memory.
