    摘要: A picture processing apparatus includes a decoder configured to decode encoded data to generate a decoded picture. A picture memory has a plurality of banks each containing a plurality of pages to which row addresses are assigned, and is configured to store the decoded picture. A bank selector is configured to divide the decoded picture into a plurality of blocks, and to select a page of a different bank as a write location for a block adjacent in at least one of either a horizontal direction or a vertical direction. A write controller is configured to write pixel data of pixels occupying even lines of each of the blocks, and pixel data of pixels occupying odd lines of each of the blocks in a column address direction of each of the page in an alternating manner.

    摘要: The present invention provides a moving picture format variable length code (VLC) decoder that decodes at a high speed. The VLC decoder includes an input data memory, which is stored with a pixel data coefficient string in moving picture format, a table reference device, which is stored with table reference data and receives memory data from the input data memory, table storage memory including a reference table, which is stored with parametric data, receives table reference data ARG from the table reference device, and transmits parametric data to the table reference device, and output data memory, which receives reference table data made from a coefficient flag output from the table reference device and the last coefficient flag.
