1. A surgical instrument control circuit, comprising:

  • a primary processor;

    a safety processor in signal communication with the primary processor; and

    a segmented circuit comprising a plurality of circuit segments in signal communication with the primary processor;

    wherein the safety processor is configured to monitor one or more parameters of the plurality of circuit segments;

    wherein the safety processor is further configured to verify the one or more parameters of the plurality of circuit segments independently of one or more control signals generated by the primary processor; and

    wherein the safety processor is further configured to disable at least one of the plurality of circuit segments when a mismatch is detected between the verification of the one or more parameters of the plurality of circuit segments and the one or more control signals generated by the primary processor.
