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.
