Designs for Increasing Reliability While Reducing Energy and Increasing Lifetime

I would like to use this opportunity to express my gratitude to everyone who sup-ported me throughout my PhD studies. First and foremost, I have to thank my research advisors, Osman Unsal and Adrian Cristal. Without their assistance and dedicated involvement in every step through-out the process, this dissertation would have never been accomplished. I was warned in my first year of PhD that I would hate my advisors before the gradu-ation. I am sincerely grateful to Osman and Adrian that they have proved that this claim has an exception.

I would also like to show my gratitude to Oguz Ergin. As being my Ms advisor, he was the one who encouraged me to start PhD, to be a researcher in the Computer Architecture area and to study on reliability. He also kindly invited me to a 3-month internship at TOBB University of Economics and Technology. His technical advises and teachings during both Ms studies and the internship have played
