Abstract: Data processing method is disclosed for processing a series of temporal processing steps [S]. The method comprises a processing step [S(n)] that generates a result [O(n)] on the basis of a set of results [O(n-1), O(n-2), . . . O(n-m)] of certain preceding processing steps [S(n-1), S(n-2), . . . S(n-m)], wherein the processing step [S] is performed in two sub-steps: a preparation sub-step [SA] and finishing sub-step [SB]. In the preparation sub-step [SA] an intermediate result [I] is determined on the basis of an incomplete set of results in which, at least the result of the nearest preceding processing step is missing. In the finishing sub-step [SB] the result [O] is determined on the basis of the intermediate result [I] and the result of the nearest preceding processing step and other results which are missing in the incomplete set of results.

Abstract: The present invention relates to a device (40) for decoding coded digital data (1) as a function of a context given by decoded digital data, comprising means (11) for the arithmetic decoding of the coded digital data that are suitable for supplying a current decoded digital data (2), control means (13) suitable for supplying a probability (4) to the arithmetic decoding means from a context word (3), and a processing circuit (12) suitable for storing a set of lines of decoded digital data and for supplying the context word (3) from previous decoded digital data. The processing circuit is suitable for causing cyclic movement of the data within the storage means such that the accesses required for the formation of the context word are made to the same locations in the storage means, thus enabling the context word to be extracted in a regular manner.
