Understanding SWCs
As discussed in Chapter 2, in the AUTOSAR standard, an SWC refers to an encapsulated piece of software with a specific function within an embedded automotive system.
An AUTOSAR software component is designed to be independent, reusable, and transferable between different electronic control units (ECUs) in a vehicle.
These SWCs are made up of a set of runnable entities (i.e., code functions) that are activated or scheduled by certain events and interact with the system through well-defined interfaces.
Important note
Imagine a car is like a big puzzle, and every part of the car needs to work together smoothly. In AUTOSAR, SWCs are like individual pieces of that puzzle. They are small, self-contained parts of the car’s computer systems, each with a specific job to do. Some of these components are grouped together within a single ECU, while others are distributed across different ECUs throughout the vehicle.
The following figure illustrates the...
