Abstract[English]
A method and system of the device may include a plurality of permute units, where each of the plurality of permute units is configured to perform local permutations on polynomial coefficients of an FHE program executed by the FHE accelerator; where the plurality of permute units are controlled by a set of permute operations, and where the permute operations are derived from instructions complied to minimize dataflows of coefficients in the FHE accelerator while utilizing variable resources of the permutation module and an internal fabric for different permutations.[French]
Un procédé et un système du dispositif peuvent comprendre une pluralité d'unités de permutation, chacune des unités de permutation étant configurée pour effectuer des permutations locales sur les coefficients polynomiaux d'un programme FHE exécuté par l'accélérateur FHE; la pluralité d'unités de permutation étant commandée par un ensemble d'opérations de permutation; et les opérations de permutation étant dérivées d'instructions compilées de manière à minimiser les flux de données associés aux coefficients dans l'accélérateur FHE tout en utilisant les ressources variables du module de permutation et un réseau d'interconnexion interne pour différentes permutations.
