Abstract
An approach to outputting 256-color pixel data more quickly than conventional systems is provided. In this approach, a word of data encoding a color bit map for up to eight pixels may be stored in a system buffer and then written to a video adapter. The video adapter is configured such that color codes for multiple pixels may be simultaneously written into the planes of the display memory of the adapter. As a result, 256-color pixel data may be more quickly drawn on a video display than in conventional systems.
