Abstract: The invention is directed to a method and an arrangement for distributing the computing load in data processing system while executing of block-based computing instructions, as well as a corresponding computer program and a corresponding computer-readable storage medium, which can be used to uniformly distribute the computing load in processors for periodically occurring computing operations. The block-based computing instructions are hereby divided into blocks, wherein a block requires a number of time-sequential incoming input values, wherein the number can be predetermined for each block. A particular area of application is the field of digital processing of multimedia signals, such as in particular audio signals, video signals, and the like.

Abstract: A method is proposed for encoding/decoding an image having rectangular blocks of pixels. The image has a height of H blocks and a width of W blocks and is divided into vertical (or horizontal) bands of blocks having the height of H (or width of W) blocks. The method includes: obtaining N processors and M coprocessors, the M coprocessors distributed over S levels, N>1, S>0 and M>S; assigning the N processors Pi to N contiguous bands BPi having sizes of Ki blocks, 0?i?N?1 and ? i = 0 N - 1 ? ? K i = W ; for every level of coprocessors s, 0?s?S?1, assigning Ms coprocessors CPs,j to Ms contiguous bands having sizes of Qs,j blocks, with: ? j = 0 M s - 1 ? ? Q s , j = W ; managing sending of first, second and third start messages, and first and second verification messages to the processors and coprocessors, according to a predetermined set of rules.

Abstract: The disclosure relates to a reverse Polish notation processing device making it possible to execute a set of instructions and implementing management of a stack whose size is variable. The device includes a storage device including a random access memory; a device for managing a stack pointer, which is a physical address, in said random access memory, associated with a reference stage of the stack; and a device for managing reference element pointer(s), which is a physical address, in said random access memory, associated with one reference element among elements of a given table contained in the stack. The processing device can execute at least one table-handling instruction with respect to the reference element pointer(s).
