Beschreibung
The task of the system architect is to take the correct early decisions despite the uncertainties.
Power-Aware Architecting provides a systematic way to support the system architect in this job. Therefore, an iterative system-level design approach is defined where iterations are based on fast and accurate estimations or predictions of area, performance and energy consumption. This method is illustrated with a concrete real life example of multi-carrier communication. This book is the result of a Ph.D. thesis, which is part of the UbiCom project at Delft University of Technology. I strongly recommend it to any engineer, expert or specialist, who is interested in designing embedded systems-on-a-chip.

Thecomplexityofembeddedsystems-on-a-chipisrapidlygrowing.Di?erentexpertsareinvolvedin the design process: application software designers, programmable core architects, on-chip com- nication engineers, analog and digital designers, deep submicron specialists and process engineers. In order to arrive at an optimum implementation compromises are needed across boundaries of the di?erent domains of expertise. Therefore, the authors of this book take the point of view of the system architect who is a generalist rather than an expert. He is responsible for the de?nition of a high level architecture, whichisgloballyoptimal.Findinganoptimumrequiresaproperbalancebetweenarea,performance and last but not least energy consumption. The challenge is not only the size of the design space but also the fact that the most important decisions are taken during the early design phases. The advantage of an early decision is that the impact on area, performance and energy consumption is large. But the disadvantage is that the available information is often limited, incomplete and inaccurate. The task of the system architect is to take the correct early decisions despite the uncertainties.
Provides a design methodology for data-dominated electronic systems, rather than a collection of particular designs Provides a high-level design method to help the designer find a balance among competing design objectives The design method provided finds an optimal solution to the hardware-software partitioning problem by means of mathematical programming The resulting partitioning is optimal with regard to energy consumption, chip area or latency (execution time) As a relevant and illustrative vehicle, the design methodology is applied to the design of an OFDM transceiver
