Context management in a graphics system. |
摘要 |
<p>A method and apparatus for the management of the data associated with multiple graphics contexts in a computer graphics rendering system. Graphics contexts are built by graphics engines and selectively saved into a context save RAM. Context switches are managed either by modifying a context base pointer to address a new section of the context save RAM, or by writing out a portion of the context save RAM to external storage and reading in a replacement context from external storage. The writing and reading process are managed by a control processor allowing the graphics engines to switch context at the same time. New contexts read from external storage automatically cause regeneration of downstream rasterization parameters. <IMAGE></p> |
