Abstract
An engine decompresses texture data belonging to a virtual texture stored in processor readable memory so that decompressed texture data may be used to update a selected sub-image of a large texture image used to render a CGI. The updated sub-image may be at any location in the larger texture image. A processor executes an application to provide control information to the engine. The control information may include commands to decode compressed texture data at source addresses and provide a stream of decompressed virtual texture data to selected sub-image destination addresses in a texture buffer used for rendering a CGI. Similarly, the engine may compress texture sub-image information and store the compressed result at a destination address.
