In this paper, we explore an approach to accelerate one of the AUTOSAR functions that is part of any Ethernet-connected AUTOSAR-based Electronic Control Units. Based on the AUTOSAR standard, a so-called SOME/IP (Scalable Service-Oriented MiddlewarE over IP) transformer is used to serialize application data before they are communicated between ECUs over an Ethernet interface. With future autonomously driven, fully connected vehicles, the need for communication will significantly increase either between different sensors distributed across the vehicle or even between the vehicles themselves. In our approach, we used a HW Co-Processor instead of the conventional software implementation used by all AUTOSAR stack suppliers for data serialization. Our approach achieves up to 33x speedup over the software implementation, which in turn will help coping with the increased demand for data communication required in modern vehicles. This approach also gives more CPU room for other real-time applications to utilize the CPU.
