Accelerated Graphics Port
     
         (AGP) A bus specification by {Intel} which gives
        low-cost 3D {graphics cards} faster access to {main memory} on
        {personal computers} than the usual PCI bus.
     
        AGP dynamically allocates the PC's normal RAM to store the
        screen image and to support {texture mapping}, {z-buffering}
        and {alpha blending}.
     
        Intel has built AGP into a {chipset} for its {Pentium II}
        microprocessor.  AGP cards are slightly longer than a PCI
        card.
     
        AGP operates at 66 {MHz}, doubled to 133 MHz, compared with
        PCI's 33 Mhz.  AGP allows for efficient use of {frame buffer}
        memory, thereby helping 2D graphics performance as well.
     
        AGP provides a coherent memory management design which allows
        scattered data in system memory to be read in rapid bursts.
        AGP reduces the overall cost of creating high-end graphics
        subsystems by using existing system memory.
