The Information and communication technology (ICT) industry is said to account for 2% of the worldwide carbon emissions - a fraction that continues to grow with the relentless push for more and more sophisticated computing equipment, c- munications infrastructure, and mobile devices. While computers evolved in the directionofhigherandhigherperformanceformostofthelatterhalfofthe20thc- tury, the late 1990's and early 2000'ssaw a new emergingfundamentalconcern that has begun to shape our day-to-day thinking in system design - power dissipation. As we elaborate in Chapter 1, a variety of factors colluded to raise power-ef?ciency as a ?rst class design concern in the designer's mind, with profound consequences all over the ?eld: semiconductor process design, circuit design, design automation tools, system and application software, all the way to large data centers. Power-ef?cient System Design originated from a desire to capture and highlight the exciting developments in the rapidly evolving ?eld of power and energy op- mization in electronic and computer based systems. Tremendous progress has been made in the last two decades, and the topic continues to be a fascinating research area. To develop a clearer focus, we have concentrated on the relatively higher level of design abstraction that is loosely called the system level. In addition to the ext- sive coverage of traditional power reduction targets such as CPU and memory, the book is distinguished by detailed coverage of relatively modern power optimization ideas focussing on components such as compilers, operating systems, servers, data centers, and graphics processors.

Memory Issues in Embedded Systems-On-Chip: Optimizations and Explorations is designed for different groups in the embedded systems-on-chip arena. First, it is designed for researchers and graduate students who wish to understand the research issues involved in memory system optimization and exploration for embedded systems-on-chip. Second, it is intended for designers of embedded systems who are migrating from a traditional micro-controllers centered, board-based design methodology to newer design methodologies using IP blocks for processor-core-based embedded systems-on-chip. Also, since Memory Issues in Embedded Systems-on-Chip: Optimization and Explorations illustrates a methodology for optimizing and exploring the memory configuration of embedded systems-on-chip, it is intended for managers and system designers who may be interested in the emerging capabilities of embedded systems-on-chip design methodologies for memory-intensive applications.
