An apparatus that allows for high capacity and fast access command queuing without requiring excess host processor overhead clock gating apparatus that is cost efficient and allows power conservation is provided. A command and its associated data to be processed by a graphics engine are formatted as data structures and first stored in system memory. A number of these data structures can be queued in system memory at any given time. Each data structure includes a header that provides information related to the data words in the data structure such as the number of the data words involved, their destination address, and others. Using the header information provided, the command and its associated data are sequentially provided to the graphics engine for processing.
