Power delivery is a growing reliability concern in micropro- cessors as the industry moves toward feature-rich, power- hungrier designs. To battle the ever-aggravating power con- sumption, modern microprocessor designers or researchers propose and apply aggressive power-saving techniques in the form of clock-gating and/or power-gating in order to oper- ate… (More)
This paper proposes Noise-Direct, a design methodology for power integrity aware floorplanning, using microarchitectural feedback to guide module placement. Stringent power constraints have led microprocessor designers to incorporate aggressive power saving techniques such as clock-gating, that place a significant burden on the power delivery network. While… (More)
In this paper, we present a novel design methodology to combat the ever-aggravating high frequency power supply noise (di/dt) in modern microprocessors. Our methodology integrates microarchitectural profiling for noise-aware floorplanning, dynamic runtime noise control to prevent unsustainable noise emergencies, as well as decap allocation; all to produce a… (More)
In this article, we propose a design methodology using two complementary techniques to address high-frequency inductive noise in the early design phase of a microprocessor. First, we propose a noise-aware floorplanning technique that uses microarchitectural profile information to create noise-aware floorplans. Second, we present the design of a dynamic… (More)
