SYSTEM, DATA STRUCTURE, AND METHOD FOR TRANSPOSING MULTI-DIMENSIONAL DATA TO SWITCH BETWEEN VERTICAL AND HORIZONTAL FILTERS

摘要

A system, processor, and method for filtering multi-dimensional data, for example, image data. A processor may receive an instruction to execute a horizontal filter by combining multi-dimensional data values horizontally aligned in a single row of a first data structure. A second data structure may include a plurality of individually addressable internal memory units. A load unit may load the horizontally aligned values in a transposed orientation for storage as vertically aligned values in a single column in the second data structure in the individually addressable memory units. Each transposed value in the single column may be separately stored in a different respective one of the individually addressable memory units. The processor may independently manipulate and combine each transposed value designated for combination by the horizontal filter by individually accessing the separate memory units.
