  4. Abstract:
  5. For many years, computer designers benefitted from Moore's law and Dennard scaling to significantly improve the speed of single-core processors. The failure of Dennard scaling pushed the computer industry toward homogenous multicore processors for the performance improvement to continue without significant increase in power consumption. Unfortunately, even homogeneous multicore processors cannot offer the level of energy efficiency required to operate all the cores at the same time in today's and especially tomorrow's technologies. As a result of lack of energy efficiency, not all the cores in a multicore processor can be functional at the same time. This phenomenon is referred to as dark silicon. In this chapter, we go over the history of computing and review some of the major changes in microprocessors. Specifically, we articulate why dark silicon is inevitable and how the performance of processors can significantly be improved in the age of dark silicon. © 2018 Elsevier Inc
