Invited Paper In this paper we consider device scaling and speed limitations on irreversible von Neumann computing that are derived from the requirement of " least energy computation. " We consider computational systems whose material realizations utilize electrons and energy barriers to represent and manipulate their binary representations of state. The(More)
Goal: Position the U.S. at the forefront of communications and computation capability beyond the physical and conceptual limitations of current technologies. Description and Scientific Rationale: Moore's Law refers to the empirical observation made in 1965 that computer processing power, based on semiconductor integrated circuits, doubles about every 18(More)
The search for alternate information processing technologies to sustain Moore's Law improvements beyond those attainable by scaling of charge-based devices encompasses several key technologies. Some of these technologies were explored at the Third Workshop on Silicon Nanoelectronics and Beyond (SNB III) held at the National Science Foundation in Washington(More)
W ith the recent introduction of dual-core processors, the wide-scale transition to parallel processing may have finally begun. How will multicore processing evolve and what will be the dominant computer architecture of the future? As technology reaches the limits of CMOS and beyond, the physical realities of computing hardware may dictate the answer to(More)
