Tornado blows hot for Wind River car standard
Steve Bush Wind River has introduced its Tornado for Automotive development system to implement the European Open System and Interface for Car Electronics (OSEK) software standard. Wind River’s existing real-time operating system (RTOS), called VxWorks, did not fit the bill. “The OSEK specification is specific, it would have required a huge amount of work to adapt VxWorks,” said Dr Neil Foster, automotive market development manager at Wind River. This difficulty stems from the scalable nature of the OSEK system kernel that can be implemented on 24 different levels. This enables its use in such diverse in-car applications as air-bags and engine management units. “The smallest OSEK kernel uses only 3k of ROM and 50bytes of RAM,” said Foster. Instead, Wind River bought into German RTOS company 3Soft (pronounced ‘Dreisoft’) last November. 3Soft has an established reputation in Europe for automotive RTOS and has been on the OSEK committee from the start. “So we knew it was compliant,” explained Foster. Since November, Wind River has added communication and network management function to the 3Soft RTOS and integrated it into Tornado, Wind Rivers’ standard development environment. Wind River is one of the ‘big three’ real-time operating system companies. The RTOS within Tornado for Automotive is called MotorWorks. VxWorks remains the company’s RTOS for in-car navigation and entertainment.
