Title (EN) CORE CHARACTERIZATION FOR PROCESSOR CORES
(FR) CARACTÉRISATION DE CŒUR POUR DES CŒURS DE PROCESSEUR
Abstract:
(EN) A circuit includes a processor and a memory. The processor executes computer-executable instructions from the memory. A core characterizer operated by the processor characterizes process variations across a set of processor cores. The core characterizer includes a core stimulator to exercise each member of the set of processor cores to cause core changes across the set of cores. A core analyzer monitors the core changes of the processor cores to generate a proximity map for the set of processor cores. The proximity map stores boost data that includes location data and the thermal data for each member of the set of processor cores. The thermal data describes thermal characteristics for each of the processor cores based on the process variations.
(FR) L’invention concerne un circuit qui comprend un processeur et une mémoire. Le processeur exécute des instructions pouvant être exécutées par ordinateur à partir de la mémoire. Un dispositif de caractérisation de cœur utilisé par le processeur caractérise des variations de processus à travers un ensemble de cœurs de processeur. Le dispositif de caractérisation de cœur comprend un dispositif de stimulation de cœur pour exercer chaque élément de l’ensemble de cœurs de processeur afin d'entraîner des changements de cœur à travers l’ensemble de cœurs. Un dispositif d’analyse de cœur surveille les changements de cœur des cœurs de processeur pour générer une carte de proximité pour l’ensemble de cœurs de processeur. La carte de proximité stocke des données d’amplification qui comprennent des données d’emplacement et les données thermiques pour chaque élément de l’ensemble de cœurs de processeur. Les données thermiques décrivent des caractéristiques thermiques pour chacun des cœurs de processeur sur la base des variations de processus.
