Abstract
A semiconductor device includes a plurality of processors and a spare processor configured to perform respective processing functions. A plurality of first switches is located at respective inputs of the plurality of processors. Each of the plurality of first switches is configured to selectively provide an input signal to a respective one of the plurality of processors and the spare processor. A first multiplexer is located at an input of the spare processor. The first multiplexer is configured to receive the input signals from each of the plurality of first switches and route, to the spare processor, a selected one of the input signals corresponding to a failed one of the plurality of processors. The spare processor is further configured to perform a processing function associated with the failed one of the plurality of processors in response to receiving the selected one of the input signals.
