摘　　要：并行计算技术是现代科技发展的重要部分,而互连网络技术则是并行机系统中尤其重要的环节。文章分析了SMP对称多处理机系统的结构模型,基于互连网络技术设计了适合一般应用需求的交叉开关,借用中断优先级的概念提出了连接请求优先级,并设计了带优先级的调度算法。通过实际应用验证了交叉开关设计思路的正确性和结构的可扩展性。最后,分析了系统的性能并指出了在并行计算领域需要进一步努力的方向。Parallel computing is important in modern technology, so is the interconnected network. This paper analyses the architecture of SMP symmetrical multi-processor system, designs a kind of crossbar for small scale multi-processor system based on the theory of advanced computer architec- ture. Brings forward the concept of require priority and designs a scheduling algorithm in considering of the priority of each processor. This paper shows the correctness and scalability of the design with an actual subject, a crossbar for SMP application system. Finally the paper analyses the shortcom- ings of the design and prospects the future work in the area of parallel computing.
