Abstract:I/O Consistency problem is one of the key issues which Multi-Cores Processor design must face. With increasing of core number and complicating of cache level, the probability of I/O coherence packets blocked would increase, which would decrease I/O system efficiency significantly. An I/O coherence maintaining method based on retransmission is proposed to improve reliability of the I/O coherence protocol. Experimental results demonstrate that this method can enhance the robustness of I/O coherence protocol effe… Show more
