【摘要】 针对分组交换网络中如何对数据缓存及对大量的多播数据存储与释放等问题,设计了一个存储管理电路。设计中使用链表的方式对两组并行输入的总线数据及数据地址进行有效管理;同时通过提取及消耗多播数,解决对网络中大量多播数据的存储和释放问题。使用5个存储器对两组总线32个端口的数据、数据地址、多播数等信息进行缓存。电路设计的仿真与综合结果表明,该存储管理电路满足对高速分组交换网中存储转发所需缓存管理的要求。更多还原

【Abstract】 Considering the action of data buffering storage,as well as multicast data storage and release,in packet switched data network,a storage management circuit is designed.According to the design,Bus data and data address of two parallel input data sets can be effectively managed in mode of list;problems of storage and release of multicast data in the network can be solved in a way of extracting and consuming;data and their address,multicast data from 32 ports of two sets of buses are put into buffer is size of 5 memories.Simulation results show that,the new design matches the actual requirement well.更多还原
