Title
(EN) POWER MANAGEMENT IN A SYSTEM ON CHIP
(FR) GESTION D'ALIMENTATION DANS UN SYSTÈME SUR PUCE
Abstract
(EN)
An electronic device (100) comprising a system on chip (101) which includes a plurality of internal subsystems (116, 118) and a power management system (108). The power management system comprises a plurality of internal voltage regulators (112, 114) arranged to supply power to the plurality of different internal subsystems, and control logic (110) which controls the supply of power from the internal voltage regulators. The electronic device further comprises an external module (102) comprising at least one external voltage regulator (104, 105). The external module is connected to the system on chip such that the external voltage regulator can selectively provide power to at least one of said internal subsystems on the system on chip.

L’invention ‌concerne‌ ‌un‌ dispositif électronique (100) comprenant un système sur puce (101) qui comprend une pluralité de sous-systèmes internes (116, 118) et un système de gestion d'alimentation (108). Le système de gestion d'alimentation comprend une pluralité de régulateurs de tension internes (112, 114) agencés pour fournir de l'énergie à la pluralité de sous-systèmes internes différents, et une logique de commande (110) qui commande l'alimentation en énergie à partir des régulateurs de tension interne. Le dispositif électronique comprend en outre un module externe (102) comprenant au moins un régulateur de tension externe (104, 105). Le module externe est connecté au système sur puce de telle sorte que le régulateur de tension externe peut fournir sélectivement de l'énergie à au moins un desdits sous-systèmes internes sur le système sur puce.
