1. A surgical instrument, comprising:

  • a sensor configured to measure a property of the surgical instrument; and

    a control circuit comprising;

    a primary processor;

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

    a segmented circuit comprising a plurality of circuit segments in signal communication with the primary processor, the plurality of circuit segments are configured to control one or more operations of the surgical instrument, wherein the safety processor is configured to transition the primary processor and at least one of the plurality of circuit segments from an active mode to a sleep mode and from the sleep mode to the active mode;

    wherein the safety processor is configured to;

    execute an independent control algorithm that controls and/or overrides signals from the plurality of circuit segments comprised in the segmented circuit and from the primary processor according to whether the property is outside a first tolerance; and

    receive reprogramming of the independent control algorithm with new parameters and/or new algorithms each time a component of the surgical instrument is modified or replaced, the new parameters and/or new algorithms defining a second tolerance and configured to control and/or override signals from said component according to whether the property is outside the second tolerance, without a subset of the plurality of circuit segments configured to control operation of said component needing to be modified or replaced.
