Analysis, Design and Management
by Akash Kumar, Henk Corporaal
Modern multimedia systems are becoming increasingly multiprocessor and heterogeneous to match the high performance and low power demands placed on them by the large number of applications. The concurrent execution of these applications causes interference and unpredictability in the performance of these systems. In Multimedia Multiprocessor Systems, an analysis mechanism is presented to accurately predict the performance of multiple applications executing concurrently. With high consumer demand the time-to-market has become significantly lower. To cope with the complexity in designing such systems, an automated design-flow is needed that can generate systems from a high-level architectural description such that they are not error-prone and consume less time. Such a design methodology is presented for multiple use-cases -- combinations of active applications. A resource manager is also presented to manage the various resources in the system, and to achieve the goals of performance prediction, admission control and budget enforcement.
This book covers a complete design trajectory for the design of multi-media systems running multiple applications; it includes both theory and practice. It is meant for all people interested in designing multi-media and other real-time multi-processor systems. It helps them to think and reason about timing requirements and offers them various modeling, analysis, design and management techniques needed to realize these complex systems first time right. The book is also meant for system level architects who want to quickly make high level estimates and system trade-offs based on solid modeling. The book is also suitable for use within a post graduate course.To this purpose we included extensive introductory chapters on trends and challenges in multi-media systems, and on the theory behind application modeling and scheduling. In particular data flow techniques are treated in some depth. In such a course the available tools will help students to get familiar with future design flows, and bring the theory into practice.
