    摘要： A microprocessor includes a direct access memory (DMA) engine which is responsive to pairs of block indices associated with one or more blocks in a first logical plane and transfers the one or more blocks between the first logical plane, a second logical plane, and a physical memory space according to the pairs of block indices. The logical planes represent two dimensional fields of data such as those found in images and videos. The microprocessor further comprises cache memory which updates its content with one or more cache-blocks which are in the neighborhood of the one or more blocks improving the operation of the cache memory by increasing cache hits. The DMA engine may further operate on n-dimensional blocks in a n-dimensional logical space. The microprocessor further includes special-purpose instructions, operative on a single-instruction-multiple-data (SIMD) computation unit, especially tailored to perform matrix operations. The SIMD may share scalar operands with an onboard single-instruction-single-data (SISD) computation unit.

    摘要： A method includes determining a lowest-score interpolation direction among a plurality of interpolation directions. The method further includes calculating a candidate pixel value by interpolating along the lowest-score interpolation direction. The method further includes applying a median function to a set of pixel values. The set of pixel values includes (a) the candidate pixel value, (b) at least one pixel value from a line of pixels that is immediately above a pixel location that is currently being interpolated, and (c) at least one pixel value from a line of pixel values that is immediately below the pixel location that is currently being interpolated.
