Abstract Hierarchical Power Management (HPM) architecture considers the limits of scaling on a power management controller, the autonomy at each die, and provides a unified view of the package to a platform. At a simplest level, HPM architecture has a supervisor and one or more supervisee power management units (PMUs) that communicate via at least two different communication fabrics. Each PMU can behave as a supervisor for a number of supervisee PMUs in a particular domain. HPM addresses these needs for products that comprise a collection of dice with varying levels of power and thermal management capabilities and needs. HPM serves as a unified mechanism than can span collection of dice of varying capability and function, which together form a traditional system-on-chip (SoC). HPM provides a basis for managing power and thermals across a diverse set of dice. La présente invention concerne une architecture de gestion de puissance hiérarchique (HPM) qui considère les limites de mise à l'échelle sur un contrôleur de gestion de puissance, l'autonomie au niveau de chaque puce et qui fournit une vue unifiée de l'ensemble à une plateforme. À un niveau le plus simple, l'architecture HPM comprend un superviseur et une ou plusieurs unités de gestion de puissance supervisées (PMU) qui communiquent par l'intermédiaire d'au moins deux tissus de communication différents. Chaque PMU peut se comporter comme un superviseur pour un certain nombre de PMU supervisées dans un domaine particulier. Les HPM traitent ces besoins pour des produits qui comprennent une collection de dés avec des niveaux variables de capacités et de besoins en termes de gestion thermique et de puissance. Le HPM sert de mécanisme unifié qui peut s'étendre à la collecte de dés de capacité et de fonction variables, qui forment ensemble un système-sur-puce classique (SoC). L'HPM fournit une base pour gérer la puissance et l'aspect thermique à travers un ensemble de dés divers.
