  Accelerated Graphics Port
  AGP
  AGP graphics
  
     <hardware, graphics> (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.
