Abstract
A method, apparatus, and system are described for processing an operation code (op-code) to be transmitted over a data path of a graphics pipeline. If the op-code comprises context state information for a first graphics context, then the context state information is transmitted to registers in the graphics pipeline over the graphics pipeline data path. If the op-code comprises a save state command, then context state information in the registers is retrieved and transmitted from the registers to a preallocated region of a frame buffer over the same graphics pipeline data path. If the op-code comprises a restore/load state command, then new context state information is loaded. Context state information for a second context can then be loaded on the graphics pipeline data path to restore or process a new context.
