Linux was created more than a decade ago. Since then, countless programmers have enhanced it, given it more features, and made it efficient, reliable, and robust. Today, thousands of businesses rely on Linux for daily client and server operations. Linux has a proven track record. Commodity pricing of microprocessors and memory devices will make future embedded designs using 32-bit architectures commonplace. Linux is already ported to these architectures and embedded Linux products exist in the marketplace. Embedded system designers adopting Linux enjoy open-source code availability, POSIX compliance, solid reliability, a large application base, and no licensing fees. These benefits, combined with commodity pricing, make Linux an excellent solution for an embedded operating system.
