摘要:
A system, method, and article of manufacture are provided for allowing direct memory access to graphics vertex data by a graphics accelerator module. First, vertex data is stored in memory. Next, an index is received which is representative of a portion of the vertex data in the memory. A location is then determined in the memory in which the portion of the vertex data is stored. Such portion of the vertex data may thereafter be directly retrieved from the determined location in the memory while bypassing a processor.
