AUTOSAR Basic Software Integration for Automotive Microprocessor Systems

Elektrobit and Microchip Technology Inc. have established a technical collaboration to provide pre-integrated AUTOSAR software suites for automotive microprocessor platforms. The joint deployment pairs basic software, device abstraction layers, and automated tooling to streamline electronic control unit development across two-wheeler and passenger vehicle architectures.

Hardware Abstraction Challenges in Automotive Embedded Software
Automotive manufacturers and Tier 1 suppliers encounter prolonged integration cycles when adapting standardized software architectures to target silicon. Configuring the Microcontroller Abstraction Layer, aligning low-level device drivers, and validating operating system execution typically require extensive manual engineering effort. These recurring setup procedures create integration bottlenecks and elevate system validation risks before application-level development can begin.

Pre-Validated Microcontroller Abstraction Layer and Operating System
The technical solution couples Microchip automotive microprocessors with the Elektrobit EB tresos software architecture. Elektrobit implements its EB tresos AutoCore operating system and generic basic software modules directly on Microchip SAMA5 microprocessors. This configuration supplies a pre-validated Microcontroller Abstraction Layer, establishing standardized hardware-independent interfaces that abstract hardware-specific registers from runtime environments and upper software layers.

Under this framework, Microchip provides silicon execution platforms, while Elektrobit delivers the middleware stack, configuration tooling, and execution logic. Elektrobit incorporates an integration-as-code methodology, converting repetitive Classic AUTOSAR configuration steps into standardized, executable scripts. This automation standardizes the generation of basic software components and creates deterministic deployment pipelines suitable for continuous integration environments.

Application Scope and Implementation Strategy
The combined architecture targets automotive control units, with initial commercial deployment addressing high-growth mobility markets in Asia, including electric two-wheelers, alongside broader vehicle platforms in North America. Providing production-ready basic software pre-configured for the SAMA5 processor family eliminates custom driver adaptation phases, allowing engineering teams to concentrate directly on domain-specific application software and vehicle diagnostics.

Support established on the SAMA5 series serves as the initial deployment baseline, with architectural compatibility planned to extend across additional Microchip microprocessor families.
