    摘要: A scalable non-blocking switching network (SN) having switches and intermediate (stages of) conductors that are used to connect a first plurality of conductors to other multiple sets of conductors in a generally unrestricted fashion within respective interconnect resources constraints. The SN can be applied in a wide range of applications, in tandem or hierarchically, to provide a large switch network used in network, routers, and programmable logic circuits. The SN is used to connect a first set of conductors, through the SN, to multiple sets of conductors in a given logic circuit hierarchy whereby the conductors in each of the multiple sets are equivalent or exchangeable, which in term, by construction, makes the first set of conductors equivalent when used in the next level of circuit hierarchy. The SN is scalable for large sized sets of conductors and can be used hierarchically to enable programmable interconnections among large sized circuits.

    摘要: A scalable non-blocking switching network (SN) having switches and intermediate (stages of) conductors that are used to connect substantially a first plurality of conductors, through a first set of switches, to a second plurality sets of conductors. The conductors in each set of the second plurality of conductors substantially connect, through a second set of switches, to a third plurality of sets of conductors. Each conductor of a set of the third plurality sets of conductors either connects, physically, to one pin in each of a plurality of functional blocks or, through a third set of switches, to a subsequent fourth plurality sets of conductors. The SN is scalable for large sized sets of conductors and can be used hierarchically in, for example, an integrated circuit or in an electronic system.

    摘要: The system and method of the present invention provides an innovative bus system of lines which can be programmed and to provide data, control and address information to the logic circuits interconnected by the bus system. This flexible structure and process enables a configurable system to be created to programmably connect one or more logic circuits, such as megacells. The programmability of the bus system enables the cascading of multiple megacells in an arbitrary fashion (i.e., wide, deep or both) and the sharing of common lines for system level communication.
