In one embodiment, the integrated circuit has a L-level permutable switching network (L-PSN) comprising L levels of intermediate conductors. The integrated circuit can be used in electronic devices, such as switching networks, routers, and programmable logic circuits, etc.

Permutable switching network with enhanced interconnectivity for multicasting signals

A L-level permutable switching network (L-PSN) having switches and multiple levels of conductors that are used to connect a first plurality of conductors to other multiple sets of conductors within respective interconnect resources constraints. The L-PSN 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 L-PSN is used to connect a first set of conductors, through the L-PSN, 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 L-PSN is scalable for large sized sets of conductors and can be used in tandem or hierarchically to enable programmable interconnections among large sized circuits.

Scalable non-blocking switching network for programmable logic

An integrated circuit having an L-level permutable switching network (L-PSN) comprising L levels of intermediate conductors and (L+2) levels of conductors for L at least equal to one. At least an (i&#x2212;1)-th level of conductors of the L-PSN comprising Inumber of conductors selectively couple to the i-th level of conductors comprising Inumber of conductors which comprise of D[i] sets of conductors in the L-PSN, where i is selected from [1:L+1], through ((I&#xd7;D[i])+I) number of switches where each conductor of the Inumber of conductors selectively couples to at least (D[i]+1) number of conductors of the Inumber of conductors, at least one conductor from each of the D[i] sets of conductors, for D[i] greater than one. The integrated circuit can be used in various electronic devices.

Enhanced permutable switching network with multicasting signals for interconnection fabric

A routing fabric using multiple levels of switching networks along with associated routing matrices to allow a more uniform and shorter interconnection or routing path among logic modules or routing modules compared with those in the conventional designs. The resulting routing fabric can be used in electronic devices, such as switching networks, routers, and programmable logic circuits, etc.

Modular routing fabric using switching networks

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.
