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.

Abstract: Methods and apparatus are provided for adaptive thermal slope control for dynamic thermal management. In one novel aspect, the device monitors and obtains sampling temperatures, calculates a thermal-slope index, determines whether the calculated thermal-slope index is greater than a predefined slope threshold, adjusts a power budget based on a thermal-slope algorithm, and applies the dynamic thermal management (DTM) adaptively based on the adjusted power budget. In one embodiment, fixed slope algorithm is used. The power budget is adjusted such that an adjusted slope of temperatures stays at a constant. In another embodiment, the time prediction algorithm is used. The power budget is adjusted such that a predicted time to reach a predefined thermal threshold stays a constant. In one embodiment, the time-prediction algorithm is a time-to-target-point (T2TP) algorithm. The T2TP is obtained using a linear equation or a LOG equation.
