Chip Aware Thermal Policy

Abstract

Methods and apparatus are provided for chip aware thermal policies. In one novel aspect, the thermal performance mapping information is generated. In one embodiment, the process obtains a set of process-dependent power data for each process corner of a semiconductor chip, profiles performance data, and selects an operating thermal policy based on the performance data. The thermal policy, based on the process-dependent power data is a mapping formula, or a combination of a mapping formula and a mapping table. In another novel aspect, chip aware thermal control is based on process-dependent power data of process corners. In one embodiment, the mapping information of process-dependent power data to a corresponding thermal policy is stored in a memory. A thermal policy is applied based on the stored mapping information and an obtained process corner information. The mapping information is applied every time the thermal policy is needed or at boot-up time.
