Linux, Real-Time Linux, & IPC
When dealing with realtime systems, IPC overhead becomes important; examines two of the best IPC mechanisms available for Linux: FIFO, shared memory. [Dr. Dobb's Journal] (November, 1999)

Team Takes Different Path to Real-time Linux
RTLinux doesn't try to change Linux into an RTOS, it instead provides a new RT kernel incorporating Linux as a low-priority thread, so the RTOS stays small, streamlined and keeps Linux as a base for common applications. [EE Times] (July 5, 2000)
