Preface
Embedded systems are becoming more and more ubiquitous in our daily lives. Since the embedded systems interact with the physical environment, they often have to behave within specified time limits. We call such systems real-time systems. Violating the timing constraints may lead to disastrous consequences. Therefore, it must be guaranteed that the time constraints are satisfied in all situations. This is an extremely difficult task, as the number of possible system states is overwhelmingly large or even infinite. In this book, we introduce some new methods to design and analyze real-time systems. Timing analysis of real-time systems is typically performed in a bottomup manner, starting with the system’s smallest components and then gradually up toward analyzing the system as a whole. The analysis on the program level aims to give each piece of program an upper limit of its execution time. On the component level (e.g., in a processor or a communication channel), many computation/communication tasks compete for the same platform, and the analysis should guarantee each of them obtains enough resource to process in time. On the system level, the analysis takes into account the interaction between the computation and communication a
