Computer systems are becoming more and more powerful and, in parallel, more and more complex. Even though increased computing performance is at the core of these developments, the complexity raises major challenges, especially in the domain of hard real-time systems. These systems need to provide a deterministic timing behavior, since unpredictable variations of timing can lead to catastrophic results.
Time-Predictable Architectures is concerned with building computers that can be used to design embedded real-time systems. Real-time embedded software requires increasingly higher performances, which leads the authors to consider processors that implement advanced mechanisms such as pipelining, out-of-order execution, branch prediction, cache memories, multithreading, multicore architectures, etc. The authors investigate the time-predictability of such schemes. This book mainly deals with hard real-time systems where it is expected that no failure occurs during the time that the system is effective (often referred to as the time of the mission in reference to aeronautics and space systems).
This book is aimed at processor architects and software developers with the intention of raising awareness of timing challenges. Engineers in aeronautics and researchers on WCET analysis will also benefit from this book.
