System and method for signature-based redundancy comparison

A method for signature-based redundancy comparison, comprising:

• 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;
• generating a delayed first output signature based on the first output signature;
• 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, by a comparator, the delayed first output signature with the delayed second output signature;
• and
• generating an error signal, a state of the error signal based upon the comparison.

A system for signature-based redundancy comparison, comprising:

• means for receiving, by a hardware-implemented master part, an input signal and means for generating, by the hardware-implemented master part, a binary output signal;
• means for generating a delayed input signal based on the input signal;
• means for generating a first output signature based on the binary output signal;
• means for generating a delayed first output signature based on the first output signature;
• means for generating a delayed binary output signal based on the delayed input signal;
• means for generating, by a checker part, a delayed second output signature based on the delayed binary output signal;
• means for comparing the delayed first output signature with the delayed second output signature;
• and
• means for generating an error signal, a state of the error signal based upon the comparison.
