Embedded Linux is the use of a Linux operating system in an embedded computer systems such as a mobile phones, personal digital assistants, media players and other consumer electronics devices, networking equipment, machine control, industrial automation, navigation equipment and medical instruments. According to a VDC survey, Linux was used by 18% of embedded engineers.[1]

Unlike desktop and server versions of Linux, embedded Linux is designed for devices with relatively limited resources, such as smaller sizes of RAM and much more limited secondary storage. Embedded Linux devices often have smaller flash memory-based secondary storage instead of a hard drive. Embedded Linux is also usually purpose-made for the required application and target hardware, and thus attempts to be the optimized form of the Linux kernel for that application. Most optimizations are done to make the OS a real-time operating system.

      The Linux Kernel Archives

      This is the primary site for the Linux kernel source, but it has much more than just Linux kernels. It is not, of course, a site for real-time or embedded Linux but it is useful if you are intent on taking Linux from the source and reformulating it to meet the needs of your embedded and/or realtime project.

      Bill Gatliff's Home Page

      Mr. Gatliff is one of the major 'guru's' of GNU/Embedded. This site is intended to be more than a personal homepage. There is information here on the work he is involved in, including the Crossgcc Wiki and gdbstubs projects. He also provides the text for most of my articles and presentations, many of which are useful as short tutorials.

      Arium Embedded Linux is Now Available

      Intel’s new small form factor Atom™ motherboards can be very inexpensive, opening up new opportunities in lower cost embedded applications not previously practical on Intel architecture. With increasing dominance of Linux in the embedded OS world, these new opportunities spark a need for specific Linux distributions and tools that meet the requirements of IA embedded development. AE Linux is a package that is targeted to developers who...

      Explanation: these links are provided as part of our EE glossary project, which seeks to identify the most prominent keywords in embedded systems, embedded software, realtime and rtos, dsp (digital signal processing), system-on-a-chip, microprocessors and microcontrollers, and other constituent elements for embedded systems. While we seek to keep most of the links up-to-date, the user is refered to other primary electronic-based search sites such as: cera2.com, embedded.com, or EDN Magazine.
