Why realtime

The processing of time-critical tasks, depends upon the capacity of the system to respond to an event, within a known and bounded interval of time.

The AV industry is building HDTV related technology on Linux, and high-end desktop systems are used by audio enthusiasts for real-time effects.

Cell phones, PDAs and MP3 players are converging into highly integrated devices requiring a large number of threads. These threads support a vast array of communications protocols (IP, Bluetooth, 802.11, GSM, CDMA, etc.). Especially the cellularbased protocols require highly deadline-sensitive operations to work reliably.

Linux?

Linux is being increasingly utilized in traditional real-time control environments including radar processing, factory automation systems, ”in the loop” process control systems, medical and instrumentation systems, and automotive control systems. Many times these systems have task level response requirements in the 10’s to hundreds of microsecond ranges, which is a level of guaranteed task response not achievable with current 2.6 Linux technology.
