Abstract

Today, every electronic control system in the car, such as Instrument Cluster, Infotainment, Anti-lock braking system, Engine Management System, Transmission Control Unit, and Body Control Management is a self-sufficient unit with its own sources like ROM, RAM memory, microprocessor or microcontroller, I/O and power supply. The idea of automotive domain controller is to replace multiple distributed ECUs with a single powerful central computer with multi-core. Multi-core processing technologies integrate multiple ECUs into one single chip. In a multi-core solution, these individual ECUs retain separated and independent processing space. However, a lot of redundant components like housing, drivers, wire and harnesses, and power supplies can be eliminated. These not only largely save cost but also the component’s weight and space. Moreover, communication between ECUs is within the processor itself instead of communicating over an external network like CAN or LIN, this will reduce the data latency and system complexity considerably.
