Embedded Linux: With friends like these, who needs enemies?

Embedded Linux: With friends like these, who needs enemies?

If embedded Linux champions are saying that embedded Linux is terrible, why would anyone want to risk their products or their company on it?

Embedded Linux is the most hyped embedded operating system ever. It is promoted as inexpensive, high quality, high productivity, reliable, widely available, and well supported. It is none of these things, as two of its greatest proponents have recently pointed out. Wind River Systems and MontaVista Software, companies that each describe themselves as "the leader" in embedded Linux, have both initiated marketing campaigns touting the horrors of using embedded Linux.

Rear-view mirror sports Windows CE-based GPS












U.S. motorists can now put a Windows CE-based navigation, safety, and entertainment system in their car's rear-view mirror. Azentek has announced the SmartMirror, featuring a 4-inch touchscreen monitor, rear-view camera, Bluetooth, built-in speakers, 3D maps, and an SD expansion slot.

 However, Michigan-based Azentek has adapted it with U.S.-specific maps from The SmartMirror is apparently based on hardware from Chinese automotive electronics maker Shenzhen Dsus, which first announced the device as the DS-400GB (right) in March.Navigon. Navigon's maps display 3D images that are said to include buildings, hills, visualizations of complex freeway interchanges, and even actual roadsign text, as shown below.

The SmartMirror is designed to replace a car's standard rear-view mirror. It features its own mirror plus, at the right, a 4-inch touchscreen with 480 x 272 pixel resolution. By default, this display shows GPS information, but the SmartMirror also has two external video inputs, which can display a vehicle's surroundings via optional rear- or side-mounted cameras.

Like a multitude of traditionally housed automotive navigation devices, the SmartMirror packs the SiRF starIII chipset. The device is based on Windows CE 4.2, has a Samsung S3C2440A processor clocked at 400MHz, and 64MB of RAM. An integral SD expansion slot accepts a 2GB card that is bundled with the unit.

According to Azentek, the SmartMirror also includes Bluetooth, through which it is capable of pairing with a mobile phone. The device offers hands-free calling, speakerphone functionality, and displays caller ID information. While Azentek does not tout multimedia playback, Shenzen Dsus said its DS-400GB is capable of playing MP3 files through its dual built-in speakers, and that functionality is likely to be available on the SmartMirror as well.
