Disclosed is a multifunction cogenerator or graphics processor for use in a graphics rendering processor. The graphics processor comprises dual graphics engines operating in parallel, with one of the engines having higher operating priority than the other. The graphics processor comprises a conics, vector, and area fill generator, a symbol generator, a bit block transfer operator, and a block texturing and complex clip mask processor synchronously controlled by a multiprocess scheduler. Included in the graphics processor is a large display memory for receiving and storing program instructions and data generated by an external host processor, internal generators and processors, and a bit mapped memory of a graphics display. The graphics processor provides hardware specific graphics functions and externally programmable general purpose processing.
