Master the fundamental concepts of real-time embedded system programming and jumpstart your embedded projects with effective design and implementation practices. This book bridges the gap between higher abstract modeling concepts and the lower-level programming aspects of embedded systems development. You gain a solid understanding of real-time embedded systems with detailed practical examples and industry wisdom on key concepts, design processes, and the available tools and methods.
Delve into the details of real-time programming so you can develop a working knowledge of the common design patterns and program structures of real-time operating systems (RTOS). The objects and services that are a part of most RTOS kernels are described and real-time system design is explored in detail. You learn how to decompose an application into units and how to combine these units with other objects and services to create standard building blocks. A rich set of ready-to-use, embedded design “building blocks” is also supplied to accelerate your development efforts and increase your productivity.
Experienced developers new to embedded systems and engineering or computer science students will both appreciate the careful balance between theory, illustrations, and practical discussions. Hard-won insights and experiences shed new light on application development, common design problems, and solutions in the embedded space. Technical managers active in software design reviews of real-time embedded systems will find this a valuable reference to the design and implementation phases.

9.2.6 Other Components
What has been presented so far is a very small set of components commonly found in available RTOS. Other service components include the SNMP component. The target system can be remotely managed over the network by using SNMP. The standard I/O library provides a common interface to write to and read from system I/O devices. The standard system library provides common interfaces to applications for memory functions and string manipulation functions. These library components make it straightforward to port applications written for other operating systems as long as they use standard interfaces. The possible services components that an RTOS can provide are limited only by imagination. The more an embedded RTOS matures the more components and options it provides to the developer. These components enable powerful embedded applications programming, while at the same time save overall development costs. Therefore, choose the RTOS wisely.
