Abstract
A method and apparatus for decreasing computer fetch time utilizes cache memory to store video data when the data is not modified by a write modifier. The video controller signals the cache controller over a control line whether the data will be modified. The data which is not modified is written to the cache memory and may be read from the cache memory when further processing is needed.
