Abstract

A method and an apparatus for controlling operations in a vehicle, at least two processors accessing at least one memory device and a simultaneous read and/or write access of the at least two processors to the identical address of the memory device during program execution being prevented. The identical address is detected by way of an address comparison, and as a function of this address comparison a signal is transmitted to at least one processor. In particular, a first signal is transmitted to a first processor and a second signal to a second processor. Program execution by at least one of the at least two processors is thereby brought to a halt by the signal, or the respective processor is halted.
