Patent attributes
Some embodiments of the invention provide a configurable integrated circuit (IC). The IC includes first and second circuits. The first circuit is a logic circuit for receiving configuration data sets and performing at least a first function when receiving a first configuration data set and a second function when receiving a second configuration data set. The second circuit communicatively couples to the first logic circuit. The second circuit is for supplying configuration data sets to the first logic circuit. The second circuit has a first set of input terminals. The integrated circuit also has a second set of input terminals for carrying data. Several the second set of input terminals overlap several of the first set of input terminals. The IC also has a set of vias, where each via connects an input terminal in the first set with an input terminal in the second set.
