Title: Real-time operating systems at higher control

Abstract

Although virtually all development of real-time operating systems focuses on the lowest of the three traditional control levels, sheet economics demands higher level real-time OSs. Meeting this demand requires a major change in the mindset of the people who have been focusing on the lowest level of control. {open_quotes}These people are trying to deal with an elephant`s tail, but they don`t realize that there is an elephant attached to it.{close_quotes} For more than three decades, the historical real-time mindset, concepts and techniques have been driven by a particular pair of contexts. First is the application context, which can be characterized as {open_quotes}small, simple, centralized, static subsystems for low-level, sampled data, monitoring and first-order control.{close_quotes} Second is the hardware context, characterized by a scarcity of hardware resources due to size, weight, power and cost considerations. Both of these contexts are changing dramatically in ways that {open_quotes}have a significant impact on the concepts and techniques of real-time computing.{close_quotes} Hardware now offers much higher performance and the real-time domain is expanding upward in the application control hierarchy.
