摘　　要：针对片上多层总线仲裁问题,基于动态规划的方法设计一种总线仲裁器,在多层总线系统中依据传输数据量和不同总线传输速率,动态分配总线类型。设计一个最小系统仿真器,模拟仲裁器的运行,实验结果证明在数据包总数在40~100范围之间时,动态分配的仲裁器可以节省25%左右的传输时间,且快速数据包越多,动态分配在减少总传输时间方面更具优势。To solve the problem of multi-layer bus arbitration on chip,designs a kind of bus arbiter based on the method of dynamic programming.In the multi-layer bus system,the bus types are allocated dynamically according to the amount of datas and the speed of different bus.In this paper,a minimum system simulator is designed to simulate the operation of the arbiter.The experimental results show that when the total number of packets is in the range of 40~100,the arbiter with dynamic allocation can save about 25% of the transmission time.And the more fast packets,the more advantages of dynamic allocation in reducing the total transmission time.
