Next Generation of Real-Time Operating Systems: Industrial Prospective

Abstract

The presentation begins with discussing major driving forces which will impact the next generation of real-time operating systems. These are: 1. Approval of the ieee posix standards 1003.4 (Real-time standard), and 1003.4a (Threads). Once these standards will be approved (expected time frame is end of 1992 to middle of 1993), every real-time operating system in order to be successful, must comply with the standard. In other words, the domination of proprietary real-time operating systems will be over! 2. Big players, such as ibm, des, Hewlett-Packard, and Sun, have entered the real-time computer battle by introducing their real-time unix operating systems. Their rt unix systems contain a fully preemptive kernel, fixed priority schedulers, and run on powerful risc-based systems. These are ibm, aix, des osf/1, sun Solaris 2.0, and hp/rt.
