Abstract: Interface module supports communication between processor systems. Communication between processor systems should chronologically burden the processor systems as little as possible. To this end, an interface module is utilized that supports the communication between two processor systems in the form of a process-parallel servicing of the two interfaces to the two processor systems.

Abstract: In a method for processing incoming code words that are accompanied by parity bits and that, in the course of being transmitted, undergo a digital attenuation and/or a code conversion for generating further code words that are to be transmitted, the code words and the parity bits are subjected to parity tests for indicating whether parity errors exist prior to the performance of the digital attenuation and/or code conversion. Then, for each of the further code words a further parity bit is generated that is also to be transmitted, but that is inverted, if the parity test of a corresponding code word has shown that a parity error exists.
