AI Technical Summary

Technical Problem

Existing automotive operating systems face challenges in efficiently managing resources and adapting to the evolution of applications, leading to suboptimal performance and increased costs due to the dichotomy between 32-bit and 64-bit architectures.

Method used

A hybrid automotive operating system that compiles applications into two groups: one optimized for performance on a first architecture (e.g., 64-bit) and another optimized for resource savings on a second architecture (e.g., 32-bit), with a method to create a software image that accounts for available execution resources on embedded electronic devices.

Benefits of technology

This approach allows for optimal execution of applications in constrained hardware environments, minimizing resource usage while ensuring performance, thereby reducing costs and improving system efficiency.

Abstract

Hybrid embedded system for road vehicles, method and corresponding program The present invention relates to an embedded computer system (SiE) within a road vehicle, which comprises an embedded electronic device (D1) comprising a processor (Px), a RAM (Mem) of predefined size and a mass memory (MS) within which a software image (IMG) is recorded for the execution of an automotive operating system and applications.The automotive operating system is compiled according to a first architecture and the applications are divided into two groups, a first group of applications compiled and optimized for operation according to said first architecture and a second group of applications compiled and optimized for operation according to a second architecture distinct from the first architecture, said software image (IMG) having been constructed to take into account available execution resources of said on-board electronic device (D1).
