Retargetable Processor System Integration into Multi-Processor System-on-Chip Platforms

The ever increasing complexity of modern electronic devices together with the continually shrinking time-to-market and product lifetimes pose enormous chip design challenges to meet flexibility, performance and energy efficiency constraints. As a consequence, the current trend is towards programmable platforms (Multi-Processor System-on-Chip Platforms, MP-SoC), which are tailored to the respective target application. In the usual case, a new platform is designed by selecting and assembling standard platform elements. However, best results can only be achieved if the processor cores and the communication modules themselves are also optimized for the target application. Effective exploration is only possible if accurate module simulators are generated automatically based on abstract specifications. As a matter of fact, CoWarea (TM)s BusCompiler allows generating accurate simulators for communication modules, and modeling languages such as LISA enable the same for processor cores. In Retargetable Processor System Integration into Multi-Processor System-on-Chip Platforms, such originally independent approaches are combined in order to enable the development of highly optimized programmable platforms. The first chapters of this book summarize the state of the art in all three involved fields separately: general system level design, communication modeling, and processor modeling. The main chapters then present a methodology and the associated tooling for enabling design space exploration as well as a successive refinement flow for the design of optimized MP-SoCs with a high degree of automation Cover......Page 1 Retargetable Processor System Integration into Multi-Processor System-on-Chip Platforms......Page 2 ISBN: 978-1-4020-8574-1......Page 4 Contents......Page 6 Foreword......Page 10 Preface......Page 12 1 Introduction......Page 14 2 SoC Design Methodologies......Page 20 3 Communication Modeling......Page 37 4 Processor Modeling......Page 53 5 Processor System Integration......Page 65 6 Successive Top-Down Refinement Flow......Page 78 7 Automatic Retargetability......Page 91 8 Debugging and Profiling......Page 101 9 Case Study......Page 118 10 Summary......Page 136 Appendix A Businterface Definition Files......Page 139 Appendix B Extended CoWare Tool Flow......Page 154 List of Figures......Page 156 References......Page 159 Index......Page 166
