摘　　要：数据队列是一种常见的硬件互联机制。阐述了数据队列在架构多处理器片上系统通信模型中的原理与运用。基于物理层到达的数据包服从泊松分布的事实,从交易的观念出发结合排队理论深入分析了模型的交易过程。使用UML、SystemC和Matlab对过程中数据流建模并仿真,将系统迟滞的理论计算值与仿真结果对比证明了该方法的有效性。Data queue is a kind of prevalent mechanism in hardware interconnection. The principles and applications of data queue in constructing communication model of Multi-Processor SoC （MPSoC） were described. Based on the truth that data package from physical layer conforms to Poisson distribution, and starting from the idea of transaction, the transaction processes of the communication model were analyzed deeply by integrating queuing theory. UML, SystemC and Matlab were used to model and simulate the data flow of the processes, The comparison of theoretical computing result of system delay with that of simulation proves the feasibility of the proposed method.
