The Design and Implementation of Crossbar in SMP Symmetrical Multi-processor System

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 basing on the theory of advanced computer architecture. 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 shortcomings of the design and prospects the future work in the area of parallel computing.
