Patent ID: 7360007

Claim:
A system, comprising: a plurality of devices; a first multiplexer logic circuit adapted to select signals from the plurality of devices; and a second multiplexer logic circuit to receive the selected signals from the first multiplexer circuit and to transmit the selected signals to chosen ones of the plurality of devices; and wherein: the first multiplexer logic circuit includes a plurality of pairs of gates, each gate having a plurality of inputs, each pair of gates having an input coupled to receive signals from a respective one of a plurality of devices, each device being coupled to send signals to a respective pair of the gates; the second multiplexer logic circuit is coupled to the first multiplexer logic circuit, the second multiplexer circuit including a plurality of multiplexers coupled to receive signals from the gates in the first multiplexer circuit, second multiplexer logic circuit including a multiplexer for each pair of gates in the first multiplexer logic circuit, each multiplexer having an output coupled to one of the devices to couple signals to one of the devices; and a control circuit is coupled to the first multiplexer logic circuit and to the second multiplexer logic circuit to generate control signals to enable selected ones of the gates of the first multiplexer logic circuit to couple signals to the second multiplexer logic circuit and to cause the second multiplexer logic circuit to select signals from the first multiplexer logic circuit to be coupled to selected ones of the devices.
