The underlying theme of my research has been to lay out a path into the future that allows us to continue to reap the benefits of Moore’s law. Toward this goal, my approach has been twofold. First, identify and address the primary bottlenecks that prevent the continuation of benefits from Moore’s law. Second, identify and address the disconnects between current hardware design and architecture methodologies and the computational usage models of the future.
