Patent CA-2952941-A1 (CA)
Inventor: GRIGORIEV GRIGORI
IPC: H03K3/84
Filed: 2016-12-30
Abstract: A method and system are used to generate random values for Physical Unclonable Function (PUF) for use in cryptographic applications. A PUF value generation apparatus comprises two dielectric breakdown based anti-fuses and at least one current limiting circuit connected between anti-fuses and power rails. Two anti-fuses are connected in parallel for value generation in programming by applying high voltage to both anti-fuses at the same time. Time for dielectric breakdown under high voltage stress is of random nature and therefore unique for each anti-fuse cell. Therefore the random time to breakdown causes one cell to break before another, causing high breakdown current through the broken cell. Once high breakdown current through one broken or programmed cell is established, a voltage drop across a current limiting circuit leads to decreased voltage across both cells, thereby slowing the time dependent breakdown process in the second cell and preventing it from breakage under programming conditions.

Abstract: L'invention concerne un procédé et un appareil de codage vidéo au moyen d'informations de mouvement dérivées d'un décodeur basées sur une mise en correspondance bilatérale ou une mise en correspondance de modèle. Selon un procédé, un indice de vecteur de mouvement (MV) initial est signalé dans un flux binaire vidéo sur un côté encodeur ou déterminé à partir du flux binaire vidéo sur un côté décodeur. Un MV sélectionné est ensuite dérivé au moyen d'une mise en correspondance bilatérale, d'une mise en correspondance de modèle, ou des deux, afin d'affiner un MV initial associé à l'indice de MV initial. Dans un autre procédé, lorsque les deux MV pour une liste 0 et une liste 1 existent dans une mise en correspondance de modèle, le MV ayant le coût le moins élevé des deux peut être utilisé pour une mise en correspondance de modèle uni-prédiction si le coût est inférieur à la mise en correspondance de modèle bi-prédiction. Selon encore un autre procédé, c'est la taille du bloc qui permet d'affiner la recherche de MV. Selon encore un autre procédé, une paire de MV candidate à la fusion est toujours utilisée pour une mise en correspondance bilatérale ou une mise en correspondance de modèle.
