Abstract

trata-se de várias modalidades de métodos e sistemas para o gerenciamento térmico ciente de eficiência energética em um dispositivo de computação portátil que contém um sistema em um chip de múltiplos processadores (?soc?) heterogêneo. devido ao fato de que os componentes de processamento individual em um soc de múltiplos processadores heterogêneo podem exibir diferentes eficiências de processamento em uma dada temperatura, as técnicas de gerenciamento térmico ciente de eficiência energética que comparam dados de desempenho dos componentes de processamento individual em suas temperaturas de operação medidas podem ser alavancadas para otimizar a qualidade de serviço (?qos?) ao ajustar os fornecimentos de potência para, realocar cargas de trabalho em oposição aos componentes de processamento com pouca eficiência energética, ou transitando o modo de potência dos mesmos. desses modos, as modalidades da solução otimizam a quantidade média da potência consumida através do soc para processar um mips de carga de trabalho.
