Memory hierarchyBuilding computers that can be used to design embedded real-time systems is the subject of this title. Real-time embedded software requires increasingly higher performances. The authors therefore consider processors that implement advanced mechanisms such as pipelining, out-of-order execution, branch prediction, cache memories, multi-threading, multicorearchitectures, etc. The authors of this book investigate the timepredictability of such schemes.Focus series in computer engineering.Real-time data processingComputer architectureReal-time data processing.Computer architecture.004.33Rochange Christine1704984Uhrig Sascha1704985Sainrat Pascal1704986MiAaPQMiAaPQMiAaPQBOOK9910813510003321Time-predictable architectures4091342UNINA
