Write readable code!
In the first 3 parts of the AUTOSAR series, we have gone through how AUTOSAR works and also learnt about its ports and interfaces, through which software components interact and communicate. In this fourth part, let’s understand the layer whose main responsibility is to consolidate all the data sent by software components before unloading them through the ports and interfaces in a predictable manner.
Its underlying functionalities include more than what we expect!
Let’s do a quick recap of how AUTOSAR works by simply looking at the diagram below.
1. Intra and Inter-ECU Communication
As we can tell from the diagram, the RTE layer in orange facilitates all the communication within the ECU and also with other ECUs by abstracting the hardware, driver and service layers at the bottom. However, if a different ECU is to be used, then the RTE has to be re-configured as it cannot be reused directly. Despite that, the usage of RTE layer simplifies the process and results in way quicker setup time compared to rewriting every lower layer. In simpler terms,
