Abstract:
A method and apparatus for buffering 2-dimensional graphical image data to be supplied to a scrolling display controller. A 2-dimensional, circularly addressed linear data buffer is used to store a portion of an entire image. The data buffer is larger than the amount of data displayed at one time. A user enters scrolling commands and the display scrolls around the data initially in the buffer. New data is loaded into the buffer as the displayed data approaches the edge of the buffered data.
