System and method for signature-based redundancy comparison

A system and method for signature-based redundancy comparison provides for receiving, by a master part, an input signal and generating, by the master part, a binary output signal, generating a delayed input signal based on the input signal, generating a first output signature based on the binary out...

Beschreibung
Zusammenfassung:	A system and method for signature-based redundancy comparison provides for receiving, by a master part, an input signal and generating, by the master part, a binary output signal, generating a delayed input signal based on the input signal, generating a first output signature based on the binary output signal, and generating a delayed first output signature based on the first output signature. The system and method further comprise generating a delayed binary output signal based on the delayed input signal, generating, by a checker part, a delayed second output signature based on the delayed binary output signal, comparing the delayed first output signature with the delayed second output signature, and generating an error signal, where the state of the error signal is based upon the comparison.
