Models

The Hello World Example contains the necessary ARXML files that you need for modeling the application.

File location: ./Examples/amsr-vector-app-example-hello-world/model

The Models provided in the Hello World Application

Model file	Use	Description
AUTOSAR_MOD_StandardTypes.arxml	Datatype Definition	Contains the AUTOSAR standard datatypes
MyAdaptiveMachine.arxml	Machine Configuration	Contains the `MachineDesign` and the `machine description`
MyAdaptiveApplication.arxml	Executable Description	Contains the `Executable`, the `StartupConfigSet` and the `Process`
MyDeployment.arxml		Contains the Process to Machine mapping

Adaptive Machine Configuration

In an MICROSAR Adaptive Application, the machine configuration is defined to ensure that the software runs correctly on the designated hardware.

File location: ./Examples/amsr-vector-app-example-hello-world/model/MyAdaptiveMachine.arxml

ARXML Element	Use	Description
`MACHINE`	Machine Definition	Defines `PROCESSORS` and references the `MACHINE-DESIGN`.
`MODE-DECLARATION-GROUP`	State Definition	Set of MachineStates and ApplicationStates that are available on this machine.
`ETHERNET-CLUSTER`	IP Definition	Defines which IP addresses should be used.
`MACHINE-DESIGN`	Communication Definition	Defines network connections, configures service discovery mechanisms and describes hardware resources.

MACHINE-DESIGN Configuration Elements

ARXML Element	Description
`COMMUNICATION-CONNECTORS`	In the `MACHINE-DESIGN` there are references to `COMMUNICATION-CONNECTORS` that can be used.
`ETHERNET-COMMUNICATION-CONNECTOR`	Example connector which can be used for SOME/IP communication.
`USER-DEFINED-COMMUNICATION-CONNECTOR`	Example IPC connector.
`SERVICE-DISCOVER-CONFIGS`	Definition of service discovery mechanisms, for example SOME/IP.
`RESOURCE-GROUPS`

Adaptive Application Configuration

The executable is the description of your executable running on the system.

File location: ./Examples/amsr-vector-app-example-hello-world/model/MyAdaptiveApplication.arxml

ARXML Element	Description
`STARTUP-CONFIG-SET`	Definition of the Startup Configuration. We defined an option `-c`. This option is not used by the application. If you would like to use this, you need to implement an argument parser.
`SCHEDULING-POLICY`
`SCHEDULING-PRIORITY`

ARXML Element

Description

STARTUP-CONFIG-SET

Definition of the Startup Configuration.

We defined an option -c. This option is not used by the application. If you would like to use this, you need to implement an argument parser.

SCHEDULING-POLICY

SCHEDULING-PRIORITY

Deployment Configuration

File location: ./Examples/amsr-vector-app-example-hello-world/model/MyDeployment.arxml

The PROCESS is the instantiation of the executable. The PROCESS is referring the executable (Models), the STARTUP-CONFIG (Models) and the MachineState (Models) in which the process should be running.

The definition on which machine which process is running is called ProcessToMachineMapping.

Additionally, in the Deployment Configuration it is defined which CPU cores should be used/not used by the PROCESS. In this case it is CPU core 0.
