Preface
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, communications infrastructure, and mobile devices. While computers evolved in the direction of higher and higher performance for most of the latter half of the 20th century, the late 1990’s and early 2000’s saw a new emerging fundamental concern 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-efficiency as a first class design concern in the designer’s mind, with profound consequences all over the field: semiconductor process design, circuit design, design automation tools, system and application software, all the way to large data centers. Power-efficient System Design originated from a desire to capture and highlight the exciting developments in the rapidly evolving field of power and energy optimization 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 relativel
