Abstract: A method for manipulating a first function of a control program of an electronic control device, using a second function. The control program is processed using a first calculation kernel of a processor, and the second function is processed by a second calculation kernel during the processing of the control program. The first function assigns a first value to a variable and writes the first value to the storage address of the variable at a first time. The second function assigns a second value to the variable, which value is written to the storage address of the variable at a second time, wherein the second value written by the first function is overwritten. At a third time, the control program reads the second value from the storage address of the variable. A control entity coordinates the times at which the storage address of the variable is accessed.

Abstract: A method for processing data of a control unit in a data communication device, which has a first memory area and a second memory area, and is connected to the control unit through an interface. Data from the control unit is transmitted to the data communication device through the interface. A value is stored identically in the first memory area and in the second memory area. The data communication device tests whether a first trigger is present, and if present, storage in the first memory area is discontinued, or the trigger class of the first trigger is tested and storage in the first memory area is discontinued only in the presence of a predefined trigger class. Subsequently, values of the data are read out from the first memory area, whereby values arriving chronologically after the first trigger are stored in the second memory area by the data communication device.
