TRANSPOSABLE REGISTER FILE

A register file structure efficiently handles matrix and image processing. The register file contains an array of data elements and has modes for accessing of multiple data values that are aligned horizontally or vertically in a data array and for accessing data having different widths for each data value. The different modes allow manipulation of a transposed array without requiring a transpose operation and permit fast horizontal or vertical filtering with parallel access and multiplications of horizontally or vertically aligned data elements.
