An electronic device (2) to control temperature and computing performance of at least one processing unit (3) is disclosed. The electronic device comprises an event generation module (2-1), an event management module (2-2) and an operating module (2-6). The event generation module (2-1) is configured to receive an internal temperature signal (S_Ti) representative of the internal temperature of the processing unit and to generate, as a function of the internal temperature signal values (S_Ti), an event signal (S_irq) indicating the need to recalculate the value of at least one control signal (S_ctrl) controlling the computing performance of the processing unit and its dissipated thermal power. The event management module (2-2) is configured to receive the event signal indicating the need to recalculate the value of the control signal, to calculate a control action for controlling the computing performance of the processing unit and the dissipated thermal power thereof, and to generate a first candidate driving signal (S_T_drv) carrying said control action. The operating module (2-6) is configured to receive the first candidate driving signal (S_T_drv) and to generate the at least one control signal (S_ctrl) as a function of the first candidate driving signal.

Abstract

An electronic device (2) to control temperature and computing performance of at least one processing unit (3) is disclosed. The electronic device comprises an event generation module (2-1), an event management module (2-2) and an operating module (2-6). The event generation module (2-1) is configured to receive an internal temperature signal (S_Ti) representative of the internal temperature of the processing unit and to generate, as a function of the internal temperature signal values (S_Ti), an event signal (S_irq) indicating the need to recalculate the value of at least one control signal (S_ctrl) controlling the computing performance of the processing unit and its dissipated thermal power. The event management module (2-2) is configured to receive the event signal indicating the need to recalculate the value of the control signal, to calculate a control action for controlling the computing performance of the processing unit and the dissipated thermal power thereof, and to generate a first candidate driving signal (S_T_drv) carrying said control action. The operating module (2-6) is configured to receive the first candidate driving signal (S_T_drv) and to generate the at least one control signal (S_ctrl) as a function of the first candidate driving signal.
L’invention concerne un dispositif électronique (2) de commande de la température et de la performance de calcul d’au moins une unité de traitement (3). Le dispositif électronique comprend un module de génération (2-1) d’événement, un module de gestion (2-2) d’événement et un module d’exploitation (2-6). Le module de génération (2-1) d’événement est configuré pour recevoir un signal de température interne (S_Ti) représentatif de la température interne de l’unité de traitement et pour générer, en fonction des valeurs du signal de température interne (S_Ti), un signal d’événement (S_irq) indiquant le besoin de recalculer la valeur d’au moins un signal de commande (S_ctrl) contrôlant la performance de calcul de l’unité de traitement et sa puissance thermique dissipée. Le module de gestion (2-2) d’événement est configuré pour recevoir le signal d’événement indiquant le besoin de recalculer la valeur du signal de commande, pour calculer une action de commande pour la commande de la performance de calcul de l’unité de traitement et sa puissance thermique dissipée, et pour générer un premier signal d’attaque candidat (S_T_drv) portant ladite action de commande. Le module d’exploitation (2-6) est configuré pour recevoir le premier signal d’attaque candidat (S_T_drv) et pour générer le signal ou les signaux de commande (S_ctrl) en fonction du premier signal d’attaque candidat.
