    摘要: Various embodiments for transferring and/or decompressing data blocks are described. In an embodiment, a memory transfer engine transfers a first data block from a nonvolatile memory to a volatile memory. A processor may decompress the transferred first data block. Furthermore, the memory transfer engine may initiate a transfer of a second data block from the nonvolatile memory to the volatile memory prior to the processor completing the decompression of the transferred first data block.

    摘要: A method and apparatus for improving the quality of MPEG video are disclosed. In a preferred embodiment, a group of pictures (GOP) is obtained and decompressed, producing an initial decompressed GOP. This initial decompressed GOP is spatially shifted to at least two shift positions. At each shift position, MPEG compression and decompression are applied, producing a resulting decompressed GOP for each shift position. The resulting decompressed GOPs are shifted back to their initial position and combined, preferably by averaging, to form an improved GOP.
