A SIGNAL PROCESSING ARRANGEMENT FOR PROVIDING A PLURALITY OF OUTPUT SAMPLES ON THE BASIS OF A SET OF INPUT SAMPLES AND A METHOD FOR PROVIDING A PLURALITY OF OUTPUT SAMPLES ON THE BASIS OF A SET OF INPUT SAMPLES

摘要

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.
