Claim 9:
10. A method of a system that includes a first processing unit and a second processing unit, which are connected to one another in a data-transmitting manner, wherein the second processing unit is configured to perform a function by executing an entire sequence of steps, the method comprising the following steps:
recognizing, by the first processing unit, that an activation condition is present; determining, by the first processing unit, whether the activation condition requires an activation of the second processing unit;
when a result of the determination is that the activation condition requires the activation of the second processing unit, activating the second processing unit by outputting an activation signal, including the activation condition, on an activation line;
determining, by the first processing unit that the function is required to be performed;
after the outputting of the activation signal and based on the determination that the function is required to be performed, the first processing unit iteratively performing the following until an end condition:
determining whether the second processing unit is in an awake state by which the second processing unit is able to proceed with the performance of the steps of the function; and
in response to a negative result of the determination of whether the second processing unit is in the awake state, proceeding with performance of a part of the sequence of steps; and

in response to the end condition, transferring to the second processing unit continued performance of the function so that a remainder of the sequence of steps not yet performed by the first processing unit is performed by the second processing unit, wherein the end condition is a positive result of the determination of whether the second processing unit is in the awake state.
