In the past decade, the proliferation of mobile devices has increased at a spectacular rate. There are now more than 3.3 billion active cell phones in the world—a device that we now all depend on in our daily lives. The current gener-ation of devices employs a combination of general-purpose processors, digital signal processors, and hardwired acceler-ators to provide giga-operations-per-second performance on milliWatt power budgets. Such heterogeneous organizations are inefficient to build and maintain, as well as waste silicon area and power. Looking forward to the next generation of mobile computing, computation requirements will increase by one to three orders of magnitude due to higher data rates, increased complexity algorithms, and greater com-putation diversity but the power requirements will be jus
