High - speed , muti - services and economy have become the major issues of the future ip backbone technology as far as thes poiflt is concerned , thes paper explores layer 3 switdrig technology which separates control component and forward compontal in the traditional roulers . two forwarding al gori thms - - - - d ata - driven mo d el and top olo gy driven model are also compared , a next generation ip backbone echno l o gy - - - - multiproto co l label switching is developed , with its operation and its deployinent in traffic engineering , c1ass - ofservce and virtual private network 本文从未来ip骨干网技术所要求的高速化、多业务支持、经济性出发,介绍了在传统路由器基础上将控制部件和转发部件分离的第三层交换技术,比较了数据驱动模型和控制驱动(拓扑驱动)模型两种转发算法,并由此引出下一代ip骨干网络技术? ?多协议标记交换,阐述了其工作原理以及在流量工程、服务等级区分和虚拟专用网中的应用。
Jx5 is a complex microprocessor , which contains cache , microcode rom , instruction prefetch unit , instruction decode unit , integer unit , mmx unit , floating point unit , page unit , bus unit , dp logic , apic and so on . it is very difficulty to test a such complicated microprocessor and receive anticipative fault coverage ratio . so , we must add dft in cpu ’ design Jx5微处理器是一款结构异常复杂的微处理器,它的内部包含有: cache 、微码rom 、指令预取部件和动态分支预测部件、指令译码部件、整数部件、多媒体部件、浮点部件、分段和分页部件、总线接口部件、双处理器接口部件、可编程中断控制部件等。
This design is the first solid - state memory system for satellite , which can confront with multi - clock sources and multi - data sources compatibly . it is the fist design that integrates all functions of data processing and control into a single programed logic device . this design can be an ip core that can bring large advantage when system upgrade in the future 本星载固存系统是我国星载固存系统中第一个采用多数据源,多时钟源进行兼容设计的单一固存系统;第一个采用ip化、参数化设计思想,采用单一逻辑编程器件做为固存系统唯一控制部件,为以后系统升级带来了很大好处;第一个采用功耗均衡思想来降低系统功耗。
