Elektrobit announced what it claims is the first automotive embedded real-time operating system (OS) and hypervisor for Infineon Technologies AG’s new Aurix TC4x microcontroller (MCU). With the EB tresos AutoCore OS and the new EB tresos Embedded Hypervisor, OEMs and Tier 1 suppliers can develop and deploy automotive E/E architectures based on the Autosar Classic standard faster. This accelerates the development of next-generation vehicles.

The shift to domain and zone-based E/E architectures goes hand in hand with the consolidation of ECUs. To reduce the complexity of electronic systems and save energy, the total number of ECUs is reduced, but on the other hand, more functions and applications are added. With the help of the EB tresos Embedded Hypervisor, applications can be combined across several virtual machines on one MCU. This accelerates innovations and serves new customer requirements.

The EB tresos AutoCore OS is an embedded multicore real-time operating system with implementation of the Autosar standard and all associated scalability classes. The EB tresos Embedded Hypervisor enables parallel execution of multiple instances of the OS and the Autosar stack on one MCU using new virtualisation features of Infineon’s Aurix TC4x MCU. This saves costs and reduces the updating effort. One application – for example, onboard diagnostics (OBD) – can thus be executed separately from other applications on the microcontroller to avoid recurring homologation costs and delays in any updates that may be required.

Infineon’s Aurix Tc4x addresses a broad range of automotive applications and the strong demand for functional integration in domain and zone-based E/E architectures. The microcontroller supports both electromobility and the advancement of automated driving through safety systems. The Aurix TC4x offers advanced connectivity and advanced safety. Samples of the Aurix TC4x family of 28nm MCUs are currently shipping to selected customers. Volume products are expected to be available in Q2 2024.
