  • Controller for processing different pixel data types stored in the same display memory by use of tag bits
    Patent number: 5828383
    Abstract: A method and apparatus is disclosed for reading display data from the same area in display memory and processing the display data as video pixel data or graphics pixel data depending on the state of at least one tag bit stored with the data. The apparatus receives display data from display memory, separates at least one tag bit from the display data and uses at least one tag bit in a controller to enable processing display data as video pixel data or graphics pixel data in each processing step. Video pixels may be corrected for missing color components with stored value if previous or next pixel in pipeline is graphics. Display memory and display memory bandwidth may be conserved by enabling video pixel data formats and graphics pixel data formats to be stored within the same display memory area.
