Abstract: An integrated coprocessor such as an accelerated processing unit (APU) generates commands for execution on a discrete coprocessor such as a discrete graphics processing unit (dGPU). Power distribution circuitry selectively provides power to the APU and the dGPU based on characteristics of workloads executing on the APU and the dGPU and based on a platform power limit that is shared by the APU and the dGPU. In some cases, the power distribution circuitry determines a first power provided to the APU and a second power provided to the dGPU. The power distribution circuitry increases the second power provided to the dGPU in response to a sum of the first and second powers being less than the platform power limit. In some cases, the power distribution circuitry modifies the power provided to the APU, the dGPU, or both in response to changes in temperatures measured by a set of sensors.

Abstract: A processing unit manages temperature by correlating readings from a plurality of external temperature sensors to a skin temperature of the processing unit, wherein the correlation is based on characteristics of a computer chassis that is to include the processing unit. The processing unit is mounted on a printed circuit board (PCB) or other substrate that is to be placed in a computer chassis. Each of a plurality of temperature sensors is placed at a different location of the PCB to provide temperature readings from a variety of locations of the PCB. A temperature controller of the processing unit receives temperature readings from the plurality of sensors and correlates the temperature readings with a skin temperature of the processing unit based on a plurality of correlation values.
