Einrichtung und Verfahren zur Steuerung der Speicherung von anzuzeigenden dekodierten Bilddaten in einem Bildspeicher |
摘要 |
<p>An apparatus for controlling a display memory for storing decoded picture data is disclosed, that comprises a data dividing portion for dividing decoded picture data as one macroblock in a vertical direction, a write address generator for generating the binary value of a write address necessary for writing the divided picture data to the display memory, a slice counter for counting the number of slice lines of picture data that has been written to the display memory, a rotate-shifter for rotating and shifting the binary value of the generated write address to the left by a first bit number corresponding to the number of slice lines counted, a means for writing the divided picture data to the display memory corresponding to the write address that has been rotated and shifted, a read address generator for generating the binary value of a read address necessary to read picture data from the display memory, a rotate-shifter for rotating and shifting the binary value of the generated read address to the left by a second bit number corresponding to output data of the slice counter, and a means for reading picture data from the display memory corresponding to the read address that has been rotated and shifted.</p> |
