Linux as an embedded OS Does Linux have potential as an embedded operating system? Should vendors of high-end commercial RTOSs quake in their Bruno Maglis? This article assesses Linux's features, robustness, limitations, and most importantly, its real-time facilities. The Linux operating system presents an attractive alternative to these options, having none of the above disadvantages. Previously used almost exclusively on the desktop computers of UNIX enthusiasts with too much free time, Linux has evolved into a sophisticated and reliable operating system that must be taken seriously. One of the most recent developments has been the addition of real-time facilities to the OS, which completes the transition of Linux from a hobbyist's toy to a valuable tool to be used by embedded system designers. These real-time facilities are not yet as sophisticated as those available in high-end RTOSs, and Linux will never be appropriate for systems that must minimise RAM and ROM use. However, for many applications, the advantages of Linux overcome these drawbacks. View the PDF document for more information.
