The AGNOSAR^® Basic Software (BSW) Stack is architected with modularity at its core, offering a scalable and adaptable foundation for embedded automotive systems. It comprises a comprehensive set of components, each engineered to address critical system functions, including:

• Communication – Supports automotive protocols for seamless inter-ECU messaging.

• Diagnostics – Enables fault detection, reporting, and system health management.

• Memory Services – Manages reliable storage and access to non-volatile memory.

• Safety Modules – Designed to meet safety-critical standards for secure operation.

• Cybersecurity – Provides layered protection against threats and unauthorized access.

• Mode Management – Controls system states and operational transitions.

• I/O Hardware Abstraction – Bridges application layers with hardware peripherals.

• Operating System (OS) – Real-time scheduling and task management.

• Runtime Environment (RTE) – Facilitates communication between Software Components and BSW modules.

Multicore SAFE Operating System 

Since an operating system manages various subsystems of the microcontroller like, memory module, interrupt controller and facilitates the execution of multiple tasks, an efficient handling of resources and faster switching between various tasks are essential for any embedded system design. Considering this, AVIN has developed a Safety-Critical Multi-core Operating System which supports both AUTOSAR and Non-AUTOSAR environments.

The key differentiators of this OS would be,

• Low CPU Time Overheads

• Enhanced Integration Features

• Business Model that supports Functional Safety Compliance

This OS is developed based on AUTOSAR R 4.2.1 and it Supports Scalability Class 4 (SC4) with Multi-Core support feature. It is designed considering safety critical aspects e.g. ISO 26262 (ASIL D) and In-built debug features for quicker analysis and easy portability onto various microcontrollers
