  摘要

  This talk ties together several projects at Harvard that strive to push

  compute performance and efficiency across a wide range of scales. For Tiny embedded systems, like the "brain" of the Harvard RoboBee, stress the limits of size and weight in addition to energy efficiency. We propose to use a fully-integrated on-chip voltage regulators, voltage-tracking clock

  generators, and a sea of hardware accelerators. In mobile applications, demands on small form factor and longer battery life motivated us to rethink the power delivery subsystem for multicore processors and to develop 'voltage stacking‘. For large-scale computing systems, In order to break through the ILP wall, we propose an automatic parallelization framework called HELIX. As a general theme, these projects explore cross-layer solutions that leverage synergistic opportunities between circuit, architecture, and software layers.
