| Summary: | All of the material in this patent application is subject to copyright protection under the copyright laws of the United States and of other countries. As of the first effective filing date of the present application, this material is protected as unpublished material.
A method and apparatus for buffering 2-dimensional graphical image data to be supplied to a scrolling display controller. A 2-dimensional, circularly addressed 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. |
