Various devices connected via MOST® interact with synchronous and asynchronous communication to create an end user experience of a rich and comfortable multimedia and infotainment environment. The devices increase in complexity and apply many consumer electronics technologies to the automotive environment. Often, two or even more embedded CPUs, sometimes of different types and with varying operating systems, are integrated in one device connected via inter-processor communication (IPC). Thus, both communications over field buses and device internal distributed communications are a paramount challenge in such types of embedded automotive devices. CETITEC meets that challenge with the Automotive Communication System to make workflows easier for OEMs as well as suppliers.
