D. Key Features of EB tresos AutoCore

i. For Hardware-Independent Products: EB tresos AutoCore Generic (ACG)

Its architecture mainly includes:

Basic Software Package: Provides the primary EB tresos AutoCore infrastructure required by any other ACG product. It includes helpers and plug-ins.
Runtime Environment (RTE): Provides a scalable and highly optimized AUTOSAR Runtime Environment (RTE). The AUTOSAR RTE supports communication between application software components and provides the main interface between application software components and basic software modules.
Communication Services: Includes AUTOSAR communication services for in-vehicle network communication. These services provide a unified interface for in-vehicle networks, independent of the communication protocol used. Every AUTOSAR communication protocol requires these services. Elektrobit provides a CAN, LIN, FlexRay, J1939, or Ethernet protocol stack containing specific network communication for various communication requirements. Together with communication services, they form a reliable solution suitable for all types of in-vehicle networks. Elektrobit ensures efficient data translation, i.e., mapping signals to PDUs, via one of the following formats:
- Signal-based format generates high-density PDUs - optimized for CAN, FlexRay, and LIN.
- Generic data serialization format (a new feature of AUTOSAR version 4.2), optimized for automotive Ethernet.
Diagnostic Protocols: Contains diagnostic-specific AUTOSAR modules. They provide an AUTOSAR-compliant implementation of Unified Diagnostic Services (UDS) for use by external diagnostic tools during development, manufacturing, and maintenance. It also includes an extension supporting On-Board Diagnostics (OBD) protocols and OBDonUDS diagnostic standards.

ii. For Hardware-Dependent Products: EB tresos AutoCore Microcontroller dependent (ACM)

Its architecture mainly includes:

Operating System (OS): Elektrobit provides the correct operating system based on the latest AUTOSAR version for each automotive Electronic Control Unit (ECU) project. If required, Elektrobit can also reach the ASIL D safety level in accordance with the functional safety requirements of ISO 26262. All of Elektrobit's industry-leading operating systems can be seamlessly integrated into EB tresos AutoCore.
Microcontroller Abstraction Layer (MCAL): MCAL includes µC-related AUTOSAR modules. Elektrobit works closely with leading semiconductor manufacturers such as NXP and Infineon to ensure Elektrobit's software runs on the latest microcontrollers.
