Redundant signal transmission

A signal transmission system, comprising:

• a plurality of signal paths in communication with an input and configured to communicate signals to an output;
• a driver steering network coupled to the input and in communication with the plurality of signal paths, wherein the driver steering network is operable to shift signals from a first signal path to a second signal path when the first signal path is inoperable;
• and
• a receiver steering network coupled to the output and in communication with the plurality of signal paths, wherein the receiver steering network is operable to shift the signals from the second signal path back to the first signal path.

A method, comprising:

• determining that a first signal path in a signal transmission system is inoperable;
• generating an error corresponding to the first signal path;
• directing the system to select an alternate second signal path in response to the generated error;
• transferring a signal to the alternate second signal path;
• and
• directing the system to transfer the signal to the first signal path after the transfer along the second signal path.

A processing system, comprising:

• a processing unit;
• a memory unit operably coupled to the processing unit by a communications bus, wherein at least one of the memory unit or the processing unit is structured as a three-dimensional multi-chip package, further comprising:
• a plurality of signal paths in communication with an input and configured to communicate signals to an output;
• a driver steering network coupled to the input and in communication with the plurality of signal paths, wherein the driver steering network is operable to shift signals from a first signal path to a second signal path when the first signal path is inoperable;
• and
• a receiver steering network coupled to the output and in communication with the plurality of signal paths, wherein the receiver steering network is operable to shift the signals from the second signal path to the output.
