| Abstract: | Based on dynamic hybrid priority algorithm,a bus arbiter has been designed for system of XDNP.According to the master access authorization slaves,the bus arbiter adjusts its own priority,greatly improving on the bus transmission efficiency.The bus arbiter supports the design method of top-down,the bus connection of Crossbar Switch and shared bus.It had been verified in modelsim and FPGA for IP-packet processing in the system of XDNP.Comparing it with other bus arbiters(cyclic priority arbiter and static hyb... |
