ABSTRACT:
Various character strings are repeatedly displayed on a graphics display. For example, strings such as "file", "edit", "view" and "help" are commonly displayed on nearly every screen. This redundancy of displayed character strings is exploited using a string cache and string caching method. A string cache stores a database of strings along with the rendered forms of the strings. The string cache stores the strings in a rendered form which for particular character strings and attributes and characteristics of the strings. The string cache is stored and accessed local to a graphics accelerator so that a single string request across a system bus activates the display of the entire string, including a display of the selected attributes and characteristics.
