1. A surgical instrument, comprising:
an electric motor;
an end effector to implement a tissue treatment; and
a control circuit, comprising:
a primary processor configured to generate a first motor activation signal based on a first sensed parameter of the surgical instrument;
a safety processor in communication with the primary processor, wherein the safety processor is configured to generate a second motor activation signal based on a second parameter of the surgical instrument;
an AND gate to generate an output signal based on the first motor activation signal and the second motor activation signal; and
a motor power switch coupled to the AND gate, the motor power switch comprising:
a closed state, wherein motor power is supplied to the electric motor; and
an open state, wherein motor power is not supplied to the electric motor, wherein the motor power switch is transitionable from the open state to the closed state based on the output signal, wherein activation of the electric motor for the tissue treatment requires generation of the first motor activation signal by the primary processor and generation of the second activation signal by the safety processor.
