Operating System: The module Os is the operating system of an AUTOSAR ECU. It is actually an extended OSEK operating system. Extensions are divided into
so-called Scalability Classes (SC1–SC4). They cover the following functionalities:
– SC1: schedule tables
– SC2: timing protection + schedule tables
– SC3: memory protection + schedule tables
– SC4: memory protection + timing protection + schedule tables
In safety-related ECUs, the OS is one of the safe- ty-related modules.
The operating system also supports (asymmetric)
multi-core microcontrollers.
