The aim of this work is to provide a communication Electronic Control Unit capable to manage greater bus load than tradition it holds, without a significant increase in the CPU load. This objective is achieved by implementing a CAN protocol with a multi-core architecture in order to manage functions triggered by events (ISR). In the proposed solution, an entire core is configured to only to manage this ISR’s, while other core is responsible for the request of functions executed in upper layers. Also the ECU shall provide the capability to connect to other high resolutions sensors and actuators, with a low cost protocol, also embedded in the multi-core architecture. The system offers a secure access method trough a XTEA encryption algorithm in order to be capable of offer diagnostic services and or re-flashing some features or the whole system.
