Research of optimization methods for inter-chips' I/O coherence processing in many-cores processor

It's the tread of many-cores processors development which support direct link interface. I/O coherence process methods of inter-chips pay important influence to I/O performance, so it's very necessary to optimize inter-chip I/O coherence processing. Firstly, the reason which I/O coherence inter-chip produced will be studied. Then presented a novel enhance synchronization I/O coherence method and boundary split I/O coherence method to optimize inter-chip I/O coherence processing in many-cores processors; Test results shown our methods can optimize performance of remote I/O operations effectually.
