Abstract:
The invention relates to a method for operating an electronic system, wherein the energy consumption of at least parts of the system is regulated such that on the basis of at least a time-related curve of the current (IFE1,..., IFEn) detected within the system, a gradient value (diFE1,..., diFEn) of the current value generated at least partially from circuitry is formed. On the basis of the gradient value, a circuit-related manipulation of at least one physical variable of the system is carried out. The invention further relates to an arrangement for carrying out the method.
Abstract:
In the method according to the invention, when the operating voltage (BS) supplied by a primary voltage source fails in a program-controlled circuit arrangement (STB), the latter is supplied with supply voltage (VS) by a standby voltage source (EQ) with a limited energy reserve. Depending on the level of the supply voltage (VS), at least one subfunction of the functions realized in the circuit arrangement (STB) is deactivated in dependence on the importance of the said functions and/or the function sequence-specific energy consumption of the said functions, the energy reserve of the standby voltage source (EQ) being optimally utilized taking account of the overall functionality.
