SYSTEMS AND METHODS FOR CORE DROOP MITIGATION BASED ON LICENSE STATE

摘要

Systems, methods, and devices are disclosed for mitigating voltage droop in a computing device. An example apparatus includes a plurality of threshold registers to store respective voltage droop thresholds, and an interface to receive a license grant message indicating a license mode for a processor core or domain. The license mode corresponds to a selected set of execution units in the processor core or domain. The apparatus also includes a voltage droop correction module to, based on the license mode indicated in the license grant message, select one of the voltage droop thresholds from the plurality of voltage droop registers, and compare a voltage droop in the processor core or domain with the selected voltage droop threshold. Based on the comparison, the apparatus triggers a voltage droop correction process.
