It appeared that the Linux kernel, combined with a small set of other free software utilities could be fit into the confines of the limited hardware space of an embedded device. A typical installation of embedded Linux takes about 2 megabyte.
Embedded Linux has these advantages compared to other embedded OSes:
- Open source
- Small footprint (Windows CE takes 21MB compared to 2MB for Embedded Linux)
- No royalty costs
- Mature and stable (over ten years of age and used in many devices)
- Well supported
Embedded Linux Consortium
In San Francisco, California on July 15, 2003 the Embedded Linux Consortium (ELC http://www.embedded-linux.org/ ), which includes IBM, Intel, Motorola, Panasonic, Samsung, Sharp, Siemens and Sony, announced a new phase of standardization activity to prepare specifications that will help product developers manage power consumption, design user interfaces and achieve real time performance for embedded Linux applications. The standards are to create a globally accepted platform offering test suites and branding to enhance the marketability of conforming products. In 2002, the ELC introduced the Embedded Linux Consortium Platform Specification (ELCPS). The target for the first draft of the ELCPS API was May 2004.
Founded in November, 1999, LinuxDevices.com has become a highly popular resource for those seeking the latest news and information relating to the growing use of Linux within embedded systems and devices of all kinds. The site publishes numerous 'quick reference guides' with information and photos of newly announced Linux-powered gadgets and devices including PDAs, mobile phones, robots, gateway/server devices, consumer electronics, and industrial applications. It also publishes lists of both free and commercial embedded Linux distributions and other related software such as embedded browsers, graphical user interfaces (GUIs), Java Virtual Machines (JVMs), and application-oriented middleware. The site's guides to Linux PDAs and Linux Smartphones are among its most popular pages.
