accelerated graphics port

[ak‚sel·ə‚rād·əd ′graf·iks ‚pȯrt]
(computer science)
A personal computer graphics bus that transfers data at a greater rate than a PCI bus.

Accelerated Graphics Port

(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.
