Abstract: A system, processor, and method are provided for encoding a data block, for example, of digital data. A processor may, from among a plurality of intra frame encoding modes each having a different direction for extrapolating already encoded pixels adjacent to the block, select an intra coding mode having a direction that most closely matches a direction of minimum pixel value change of the block. The processor may compute a predicted intra frame encoding residual data for the block associated with the selected mode based on the difference between the direction of the selected intra frame encoding mode and the direction of minimum pixel value change of the block. The processor may compute inter frame encoding residual data and compare the intra and inter frame encoding residual data. The processor may compress the data block using the intra or inter frame encoding having the smaller residual data.

Abstract: A system and method of data transfer that collapses a multi-dimensional data array while preserving neighboring connectivity. One or more program instructions may be received that request input data comprising a sub-set of data elements from a first data array in an external memory. The sub-set of data elements may be transferred from the first data array in the external memory to a second data array in an internal memory. The retrieved sub-set of requested data elements may be stored in the second array in respective positions translated from the positions in the first array by a plurality of omitted rows and columns from the first data array from which no data elements are requested.

Abstract: A system, processor, and method are provided for spatially encoding a data block of digital video, such as an image frame, video stream, or other digital data. A processor may receive an uncompressed data block defining values for a set of pixels. A mode decision unit may determine a direction of pixel value change between the set of pixels and a set of adjacent pixels which belong to one or more previously encoded data blocks. The mode decision unit may compare the direction of pixel value change with each of a predefined plurality of different mode directions and may select the mode direction that most closely matches a direction of minimum pixel value change. A mode prediction unit may extrapolate values from the set of adjacent pixels in the selected mode direction. An encoder may use the extrapolated values to generate compressed data representing the uncompressed data block.
