Instrumentation & Control Systems: Why Use Linux in Embedded and Real-Time Systems?

“Today’s highly sophisticated and empowered intelligent embedded
systems, which are based on the newest chips and hardware
capabilities, require nothing less than the power and
sophistication of high-end operating systems (OSs) like
Windowstrademark 98 or Windows NT. However, embedded
systems
also require extremely high reliability for
nonstop, unattended operation, plus the customization of the OS to
match the application’s unique requirements.”

“You might think that Linux, like Windows, would be large and
highly demanding of system resources. However, unlike Windows,
Linux is inherently modular and can easily be scaled to compact
configurations-barely larger than DOS-that can fit on a single
floppy. What’s more, because Linux source code is freely available,
it’s relatively easy to customize the operating system according to
unique embedded system requirements.”

“Open-source Linux has created a new OS development and support
paradigm, wherein thousands of developers continually contribute to
a constantly evolving Linux. Also, there are dozens of software
companies that are eager to support the needs of Linux developers
building a variety of applications, ranging from factory automation
to deeply embedded devices.”
