As embedded technology evolves, it inevitably grows more specialized. So it goes with embedded operating systems, which now contain more than the usual features of interrupt handling and memory management, and have come to include middleware, such as graphics and networking.
"It's a natural evolution of the embedded operating systems market," notes David Barnett, director of product marketing for Green Hills Software, Inc. "As we solve the horizontal problems, and as the applications get more complex, the trend is to provide more standard components for customers."
Indeed, makers of embedded operating systems now market products for a variety of applications from consumer electronics to avionics. It's a far cry from the way embedded technology was marketed a decade ago, but users gain a level of integration that might otherwise chew up hundreds of hours of development time.
Following are three of the latest entries into the application-specific EOS market.
WE ARE HERE!!!Green Hills Flies with Airbus
Green Hills Software engineers say that the key difference between their Integrity-178B operating system and that of competitors is that it is FAA certified. The product, which complies with the ARINC 653 aviation standards for partitioned operating systems, is now undergoing security evaluation to Common Criteria Evaluation Assurance Level 6+ (EAL6). (The company claims no operating system has previously been certified beyond EAL5.) In June, Green Hills announced Integrity-178B would be deployed aboard Airbus A380 in its engine monitoring and navigation systems. Read†more information about Integrity-178B.
MontaVista Powers Moto Handset
MontaVista's Mobilinux 4.0, unveiled in April, delivers mobile phone reference architectures to handset manufacturers that want to develop Linux-based phones. The reference architectures include mobile software components and are built atop the Linux 2.6 kernel. In June, MontaVista said that the new operating system will serve in the Motorola E895, a handset that combines a 1.3-megapixel camera with video playback and streaming video, as well as Bluetooth printing, Bluetooth peer-to-peer gaming, and a Bluetooth stereo headset.

WE ARE HERE!!!Wind River Launches Refueling Tanker
At the Paris Air Show in June, Wind River unveiled its new Aerospace and Defense Field Operations product line, which includes the company's Platform Safety Critical ARINC 653 operating system. Based on VxWorks AE653, the operating system distinguishes itself by reportedly being the only such platform to be ARINC 653 compliant. It is set to serve in the Boeing KC-767A mission control system, which manages flight guidance, navigation, and communication capabilities for the aircraft.†Read†more information about the Wind River Platform Safety Critical ARINC 653 operating system.
