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.
- Accelerated learning
noun an intensive and shortened course of study
- Accelerated reader
a teaching device into which a page of reading material is inserted and advanced one line at a time, gradually increasing the speed to accelerate and improve one’s rate of reading comprehension.
- Accelerating universe
accelerating universe A phrase used to refer to the discovery that the Hubble expansion is not slowing down, as one would expect if only gravity were acting on the galaxies, but is actually speeding up as time goes by. (See dark energy.)
the act of ; increase of speed or velocity. a change in velocity. Mechanics. the time rate of change of velocity with respect to magnitude or direction; the derivative of velocity with respect to time.
