Runtime environment
The RTE plays a critical role in the AUTOSAR architecture; it is the middleware layer facilitating communication between SWCs in the application layer and the BSW layer. The RTE serves as an abstraction layer, enabling the exchange of data and signals between SWCs without needing to know the underlying hardware or software details.
This abstraction enables SWCs to be designed, developed, and tested independently of each other and the target hardware platform. In addition, the RTE provides a range of services, such as data marshaling, data transformation, and event-driven communication, further enhancing the efficiency and robustness of the overall system.
Before discussing RTE further, we need to get familiar with the virtual functional bus (VFB) concept so that we can better understand the RTE.
Understanding the VFB concept
The VFB is an abstract concept in AUTOSAR that represents the communication infrastructure for SWCs in the application layer. It...
