We thank Manju Hegde for proposing the book project, BaoHuong Phan and Todd Green for their management and input from the AMD and Morgan Kaufmann sides of the project, and Jay Owen for connecting the participants on this project with each other. On the technical side, we thank Jay Cornwall for his thorough work editing much of this text, and we thank Joachim Deguara, Takahiro Harada, Justin Hensley, Marc Romankewicz, and Byunghyun Jang for their significant contributions to individual chapters, particularly the sequence of case studies that could not have been produced without their help. Also instrumental were Jari Nikara, Tomi Aarnio, and Eero Aho from the Nokia Research Center and Janne Pietiäinen from the Tampere University of Technology.
