1. A data verifier system, comprising:
a first processing circuitry configured to perform a safety operation, the safety operation comprising:
determining from sensor data representing a second processing circuitry factor whether a verification criterion is satisfied; and
if the verification criterion is satisfied, generate a signal representing an approval for the second processing circuitry to perform a safety critical task;
wherein the second processing circuitry factor comprises
a temperature of the second processing circuitry,
a processing speed of the second processing circuitry,
an interconnect integrity of an interconnect of the second processing circuitry,
a voltage of a portion of the second processing circuitry compared to a reference voltage, or a current drawn into or exiting from the second processing circuitry;
wherein if the verification criterion is satisfied, the first processing circuitry or the second processing circuitry is configured to register the second processing circuitry with a task scheduler to perform the safety critical task, and wherein if the verification criterion is not satisfied, the first processing circuitry and the second processing circuitry are configured to not register the second processing circuitry with the task scheduler to perform the safety critical task.
