The Refresh Efficiency on Difference Processor Cache Architecture

Cache is important for the performance of processor. With the multi-core developed, cache architecture for the performance of multi-core processor has begun to emerge. Through the result of running a test program for parallel computing obtains the phenomenon, this article analyses the reason of it occurred. It summarizes that the L2 cache architecture has an impact the performance of multi-core processor. The result proves the shared L2 cache architecture, which has effect on the performance of multi-core processor, when all of cores are full load.
