Display graphics adapter for processing different pixel sizes in a windowing system |
摘要 |
A graphics adapter having a processor for processing pixel data is provided. The processor transfers the processed data to the graphics memory in sets of slices of pixel data where each transfer provides several slices, each slice being from a unique pixel. In an alternative embodiment, the storage of the processed data is accomplished within a plurality of memory banks, each of the memory banks being used to store slices of consecutive pixels. The invention further provides for concurrently displaying images having different color depths. This is achieved by a method of organizing data of different pixel depths such that they can be interpreted correctly. Furthermore, the invention provides for double buffering the processed data to get a smooth transition from one image to another.
