    • The present invention provides a method and a system for connecting together, in a VLSI chip, a plurality of macros which require data flow connections between each other. A simple standard interface is realised between all macros. Any number of macros can be connected together, also allowing concurrent transactions between 4 or more macros using a cross-bar switch. Each macro may be a master (capable of requesting connections), a slave (capable of receiving connections from a master) or both. The centralised inter-connect logic includes three major components: the cross-bar switch, which makes the connections between the macros, the address decoder, which determines which slave each master wishes to connect to and an arbiter, which arbitrates between the macros when two or more masters request a connection simultaneously.
    • 本发明提供了一种用于在VLSI芯片中将需要相互数据流连接的多个宏连接在一起的方法和系统。 所有宏之间实现简单的标准接口。 任何数量的宏都可以连接在一起,也允许使用交叉开关的4个或更多宏之间的并发事务。 每个宏可以是主(能够请求连接),从机(能够从主机接收连接)或两者。 集中式互连逻辑包括三个主要部分:交叉开关,它们使得宏之间的连接,地址解码器确定每个主机希望连接的从属和仲裁器,它们在宏之间进行仲裁 或更多的主人同时请求连接。

    • An expandable mandrel for holding a workpiece, including a mandrel body having an interior surface and an exterior surface. The interior surface defines at least first and second interior regions separated by a transition surface, the first region having a cross sectional area greater than a cross-sectional area of the second region. A plurality of slots extend between the interior surface and the exterior surface. A slave actuator having a bearing surface is at least partially disposed in the first region, and a master actuator is provided for urging the bearing surface against the transition surface to expand the mandrel against the workpiece.
    • 一种用于保持工件的可膨胀心轴,包括具有内表面和外表面的心轴本体。 内表面限定由过渡表面分开的至少第一和第二内部区域,第一区域具有大于第二区域的横截面面积的横截面面积。 多个狭槽在内表面和外表面之间延伸。 具有轴承表面的从动致动器至少部分地布置在第一区域中,并且提供主致动器用于将支承表面压靠过渡表面以使心轴相对于工件膨胀。
