    • Method for an electronic device (IT) that is controllable in at least one operating state (OP) and one standby state (SBY), with which a main processing unit (MPU) controls the operating state (OP) and a preprocessing unit (PPU) controls the standby state (SBY), such that, by means of the preprocessing unit (PPU), the main processing unit (MPU) and, to some extent, the functional units of the electronic device (IT) that are implemented by circuitry are switched by the control into at least one state having reduced energy consumption. An advantage can be seen in the fact that, by using a preprocessing unit (PPU), in the operating state of “standby” (SBY) the total energy consumption of the electronic device (IT) is reduced, both due to the significantly reduced energy consumption of a preprocessor (PPE) in the preprocessing unit (PPU) and to the units (MPU) that have been switched by the control into a state having reduced energy consumption, and the electronic device can therefore be operated more economically. An additional advantage is that the reduction of the energy consumption is achieved exclusively by circuitry measures and that no implementations must be included in the programs of the electronic device (IT).
    • 一种在至少一个操作状态(OP)和一个待机状态(SBY)中可控制的电子设备(IT)的方法,主处理单元(MPU)通过该方式控制操作状态(OP)和预处理单元(PPU) )控制待机状态(SBY),使得通过预处理单元(PPU),主处理单元(MPU)以及在一定程度上由电路实现的电子设备(IT)的功能单元 由控制器切换成具有降低的能量消耗的至少一个状态。 可以看出,通过使用预处理单元(PPU),在“待机”(SBY)的运行状态下,电子设备(IT)的总能量消耗减少,这两者都由于显着降低 预处理单元(PPU)中的预处理器(PPE)和由控制器切换到具有降低的能量消耗的状态的单元(MPU)的能量消耗,因此可以更经济地操作电子设备。 额外的优点在于,能量消耗的降低完全由电路测量实现,并且在电子设备(IT)的程序中不包括任何实现。
