Overview

The automotive industry relies heavily on Realtime operating systems (RTOS) to handle safety-critical applications that require precise timing and responsiveness. The adoption of RTOS has led to increased software quality, reduced development costs, and shorter time-to-market for new products.

Realtime Operating Systems and the Automotive Industry:

• RTOS is designed to handle specific needs in the automotive industry, such as providing real-time data to the driver in the form of infotainment systems. These systems (RTOS) ensure that critical tasks are executed on time and without delay, providing a reliable and efficient solution for the automotive industry.

OSEK and AUTOSAR Standards:

• The automotive industry has adopted two standards for RTOS. The OSEK (Open Systems and their Interfaces for Electronics in Motor Vehicles) standard was developed in the 1990s and defines a set of specifications for an RTOS in the automotive industry. AUTOSAR (Automotive Open System Architecture) which follows OSEK's principles, is a newer standard that has been adopted by the industry to create a common platform for the development of automotive software. AUTOSAR provides a standard methodology for designing, implementing, and integrating software components in vehicles.

Our project, which is the design of an AUTOSAR-compliant RTOS for next-generation eMobility, ADAS, automotive E/E architectures, and affordable AI applications, is essential for the automotive industry. By providing an RTOS that complies with the industry-standard AUTOSAR methodology, we ensure that our software is reliable, maintainable, and compatible with other AUTOSAR-compliant software. Additionally, our RTOS supports next-generation hardware accelerators, which are necessary for the efficient and effective functioning of these systems.

? Objective

The project aims to support new hardware accelerators, such as the PPU (Parallel Processing Unit) and cDSP (Programmable digital signal processing for the ADC signals).
