Resource access protocols,s, a main memory area, a file, or a set of registers of a peripheral device. A resource dedicated to a particular process is said to be ., whereas a resource that can be used by more tasks is called a .. A shared resource protected against concurrent accesses is called an ..

Kernel design issues,ontrol applications. For didactical purposes, we illustrate the structure and the main components of a small real-time kernel, called DICK (.dactic .ernel), mostly written in C language, which is able to handle periodic and aperiodic tasks with explicit time constraints. The problem of time predicta

Handling overload conditions,This chapter deals with the problem of scheduling real-time tasks in overload conditions; that is, in those critical situations in which the computational demand requested by the task set exceeds the time available on the processor, and hence not all tasks can complete within their deadlines.

Periodic task scheduling,m sensory data acquisition, low-level servoing, control loops, action planning, and system monitoring. Such activities need to be cyclically executed at specific rates, which can be derived from the application requirements. Some specific examples of real-time applications are illustrated in Chapter 10.

Dynamic priority servers,different service methods are introduced, whose objective is to reduce the average response time of aperiodic requests without compromising the schedulability of hard periodic tasks. Periodic tasks are scheduled by the Earliest Deadline First (EDF) algorithm.
