Abstract:
A rendering processing system, comprising:rendering operation circuitry for performing an operation for generating a plurality of pixel data corresponding to a plurality of pixels constituting a screen; a first memory receiving and storing the plurality of pixel data output from said rendering operation circuitry, each of said plurality of pixel data including three-color information of red, blue and green of a corresponding pixel and &agr; value information representing transparency of said corresponding pixel; a second memory for storing supplied pixel data and for outputting stored pixel data to a display unit for display of an image; a transfer circuit removing prescribed data from each of the pixel data stored in said first memory, and generating transfer pixel data corresponding to the pixel data for transference and storage to said second memory, said prescribed data including at least said &agr; value information; and a memory control circuit for controlling operations of the first and second memories, wherein said memory control circuit includes means for performing output of the data from said second memory to said display unit and writing of the pixel data from said first memory to said second memory in an interleaved manner.
