Abstract

An area-efficient dynamic thermal management (DTM) unit using multiplying delay-locked loop (MDLL) with shared DLL scheme is proposed for per-core DTM in many-core processors. The proposed DTM unit consists of a MDLL and a shared-DLL-based temperature sensor. The shared DLL takes part in both temperature sensing and frequency scaling while reducing the size of whole DTM unit. The area is reduced by 54.4% compared to the design in which a phase-locked loop (PLL) is used without any optimization scheme.
