Making USB a More Energy-Efficient Interconnect

CONCLUSION

Like the original '64 Mustang, USB is a classic. Although it has been widely successful, the time has come for an "energy-efficiency" overhaul. The key attributes that contributed to USB's success (simple, low cost, decent bandwidth) needed to be preserved while at the same time modernizing and enhancing this interconnect for today's environment where "green-ness" and "power efficiency" have become equally important.

We have demonstrated techniques and offered suggestions that transform USB into a much more energy-efficient interconnect, primarily by optimizing the idle behavior of USB host controllers and devices. This complements USB's relatively good bandwidth per watt characteristics to produce a robust and power-friendly solution.
