A STUDY OF CAR INFORMATION SYSTEM FOR ITS
Mariko Okude, Yui Endo, K Nakamura, T Kamiwaki · 2001
This paper presents a driver information system that uses Dependable Autonomous hard Real-time MAnagement (DARMA) technology which is able to operate multiplexed operating systems on a single processor. The system features an open operating system (OS) that operates multimedia telematics applications. It also has a very reliable real-time OS (RTOS) which operates mission-critical software such as a legacy navigation software. A common device function is developed for peripheral device competition problems between the two operating systems, while common data function is developed to coordinate operations between these multimedia services. The paper also describes a prototype system which is verified by the operation of some application software.
