| Research Abstract |
Performance of modern microprocessors is often constrained by the chip temperature. Therefore, we studied a method to reduce chip temperature for performance improvement of microprocessors. We focused on Turbo Mode, which is widely used in modern microprocessors. Our technique is to use Activity Migration for upgrading the maximum CPU frequency during Turbo Mode. We developed a method to apply Activity Migration to a microprocessor with spatial fine granularity and its design methodology. We evaluated our technique with the combination of some simulators. The result shows that our technique achieves 14.5% of performance improvement in exchange for 2.8% of area increase.
