I Introducing INtime software This part acquaints you with INtime software: its components, how they’re put together, and how they work with Windows to run RT applications. This part contains: Chapter 1: Overview Describes how INtime software works together with Windows to create and run RT applications, and lists INtime software’s features. It also tells you where to find detailed information about INtime software topics. Note Read this chapter first. It introduces you to all the basic INtime software concepts and tells you where to find detailed information. Chapter 2: Understanding INtime software architecture Explains how INtime’s RT kernel works with Windows to provide RT functionality. It also lists and describes INtime components. Chapter 3: About INtime software’s RT kernel Describes the RT kernel and its objects, the basic building blocks that application programs manipulate. Chapter 4: About RT programming Describes processes unique to RT programming. Chapter 5: Designing RT applications Provides general guidelines for RT system design. 1
