Design and Inmplementation of RTE Generator for Automotive Embedded Software

Runtime environment is located in a middle layer of the AUTOSAR architecture to provide infrastructure services that enable not only the communication between software components, but also between software components and basic software components. An RTE generator is an automated generation tool for the AUTOSAR specification based RTE according to the ECU configuration. It generates a communication API function for software components and basic software components like OS and COM of the application. The availability and accuracy of the RTE generator are important for the automobile software which is based on the AUTOSAR architecture. This paper proposes an architectural design of an RTE generator for the auto-generation of the AUTOSAR based RTE. Then an RTE code generator is implemented based on the proposed architecture to generate RTE code for a simple AUTOSAR application. The generated RTE code shows that the designed and implemented RTE generator correctly reflects the configuration of the test application.
