1. A graphics subsystem for rendering texture information representative of graphics primitive on a computer display, comprising:

  • a host processor for generating display list information of parameter values defining said primitives;

    a system memory coupled to said host processor for storing said display list information;

    a graphics processor coupled to said host processor and said system memory for processing said texture map information;

    wherein said graphics processor includes;

    a register file for storing said display list of parameter values;

    a polygon engine coupled to said register file for generating polygons responsive to said primitives; and

    a texture control unit coupled to said register file for receiving said texture information and generating texture maps representative of said graphics primitives, comprising;

    a texture engine for receiving the initial and incremental values of a texture to be fetched from said system memory, said texture engine further receiving polygon size information from said register file in order to track the exact number of texels to complete a primitive to be rendered; and

    a static random access memory device disposed within said texture control unit for storing texture maps used to fill in polygons drawn by said polygon engine.
