Abstract:
1. A programmable integrated circuit having a bus structure for a cross-connection network for data (DCC network), comprising: a plurality of stations having an input station, one or more intermediate stations, and a destination station, each station comprising a pipeline register, the input station serializing data at a first frequency X, the one or more intermediate stations registering the serialized data at a second frequency Y, the destination station deserializing the data at a third frequency Z, the first frequency and the second frequency forming a first frequency ratio Y/X, the second frequency and the third frequency forming a second frequency ratio Y/Z, the input station including a first multiplexer coupled between a first serializer and a first pipeline register, a first multiplexer having a plurality of inputs, an output, at least one select signal, the at least one select signal for selecting between the first serializer, other serializers, and other pipeline registers to a first pipeline register; and connectors selectively joining each pipeline register at the corresponding station based on a select signal for selecting between special-purpose circuits, other pipeline registers, and logic circuits.
