Abstract

Divers modes de réalisation de procédés et systèmes de réaffectation en fonction du mode de charges de travail dans un dispositif informatique portable (" pcd ") qui contient un système multi-processeur hétérogène sur une puce ("soc"), sont divulgués. Du fait que les composants de traitement individuels dans un système multiprocesseur hétérogène soc, peuvent présenter des puissances ou des capacités de rendement différentes, et que plus d'un des composants de traitement peut être capables de traiter un bloc de code donné, les systèmes et méthodologies de réaffectation en fonction du mode peuvent être exploités pour optimiser la qualité de service ("qos") par l'affection de charges de travail en temps réel, ou pratiquement en temps réel, aux composants de traitement les plus aptes à traiter le bloc de code d'une manière qui satisfasse les objectifs de performance d'un mode de fonctionnement. Les modes opérationnels peuvent être déterminés par la reconnaissance d'une ou de plusieurs conditions de décision de mode dans le pcd.
