Understanding layered software architecture in AUTOSAR

We can visualize the layered software architecture in AUTOSAR as a multi-story building, where each floor serves a distinct purpose and has its own set of responsibilities. In this analogy, the floors represent the different layers of the AUTOSAR software architecture, and the rooms on each floor represent the modules within each layer:

• Basic software (BSW) layer (basement): This floor represents the foundation of the building, providing essential services such as plumbing, electrical systems, and heating. Similarly, this layer contains modules that manage low-level tasks such as communication, diagnostic services, memory management, and operating system (OS) functionalities.
• Runtime environment (ground floor): This floor serves as the hallway that connects the ground floor to the upper floor, facilitating smooth movement between them. The runtime environment (RTE) in AUTOSAR facilitates communication between SWCs in...
