Zusammenfassung:A signal processing arrangement (200) for providing a plurality of output samples (280) on the basis of a set of input samples (250), comprising: a sample distribution logic (210) configured to provide a plurality of subsets of the set of input samples to a plurality of processing cores (220) which perform processing operations associated with different time shifts (298), wherein the sample distribution logic comprises a hierarchical tree structure (240) having a plurality of hierarchical levels (240a, 240b, 240c), wherein a respective splitting node (230d, 230e, 230f) of a lowest hierarchical level (240c) is configured to provide, from the input samples of the respective splitting node of a lowest hierarchical level, two or more subsets to a plurality of processing cores coupled to the respective splitting node of the lowest hierarchical level, wherein a respective splitting node of a given hierarchical level, which is higher than the lowest hierarchical level, is configured to provide, from the input samples of the respective splitting node of the given hierarchical level, two or more subsets to a plurality of subtrees coupled to the respective splitting node of the given hierarchical level, wherein the respective splitting node is configured to select each subset so as to be in accordance with a range of time shifts associated with the processing cores coupled to the corresponding subtree, and the plurality of processing cores configured to perform processing operations associated with different time shifts in parallel, in order to obtain the output samples. L'invention concerne un agencement de traitement de signal (200) pour fournir une pluralité d'échantillons de sortie (280) sur la base d'un ensemble d'échantillons d'entrée (250), comprenant : une logique de distribution d'échantillons (210) configurée pour fournir une pluralité de sous-ensembles de l'ensemble d'échantillons d'entrée à une pluralité de centres de traitement (220) qui effectuent des opérations de traitement associées à différents décalages temporels (298), la logique de distribution d'échantillons comprenant une structure d'arbre hiérarchique (240) ayant une pluralité de niveaux hiérarchiques (240a, 240b, 240c), un nœud de division respectif (230d, 230e, 230f) d'un niveau hiérarchique le plus bas (240c) étant configuré pour fournir, à partir des échantillons d'entrée du nœud de division respectif d'un niveau hiérarchique le plus bas, au moins deux sous-ensembles à une pluralité de cœ
