  Graphics processing unit - Wikipedia, the free encyclopedia
Modern GPUs are very efficient at manipulating and displaying computer graphics, and their highly parallel structure makes them more effective than typical CPUs for a range of complex algorithms.
Modern GPUs are descended from the monolithic graphic chips of the late 1970s and 1980s.
A new concept application for GPU's is that of Stream processing and the General Purpose Graphics Processing Unit.

 GPU - Graphics Processing Unit
Graphics Processing Unit Like the CPU (central processing unit), it is a single-chip processor.
Referring to Graphics Processor Unit, a GPU takes on the task of working with Transform and Lighting (TandL) away from the CPU so it can focus on more important things such as AI.

 Image producing device - Patent 7079146
The graphic processor includes two buffers for storing graphic contexts corresponding to the graphic element lists together with identification information on the graphic contexts, and a unit for reading a specific graphic context from the buffers upon inputting the graphic element lists from the arbitrator to conduct the graphic processing.
The graphic processing means includes a large number of circuits which are disposed in parallel with each other, and the parallel arrangement of the large number of circuits is compatible with the rendering processing where simple processing is frequently repeated.
The graphic region setting information is directed to the offset coordinates of the graphic region and the coordinates of a drawing clipping region for canceling the drawing in the case where the coordinates of the polygon exist in the exterior of the graphic region.

 nV News - NVIDIA GeForce3 Preview - Lightspeed Memory Architecture
NVIDIA is taking graphics memory architecture to the next level and is employing the use of a crossbar to maximize the efficiency of data transfer between the graphics processing unit and the graphics memory on the GeForce3.
Since the load and store units on the graphics processing unit are capable of issuing a memory load or a store on every cycle, the memory controllers should be capable of processing these requests at the same rate.
If the graphics processing unit determines that the region is going to be occluded, then all the representative geometry and rendering representing that region can be bypassed.

 Real-Time Water Simulation Using Fast Fourier Transforms Implemented on a Graphics Processing Unit, 07-9433   (Site not responding. Last check: 2007-10-15)
The capability of the GPU to increase the efficiency of the Fast Fourier Transform (FFT), a numerical transform used widely in various fields of engineering, was researched by implementing an FFT that runs solely on a GPU.
The performance benefits of offloading the processing to the GPU were demonstrated by using the FFT to create the height field of a water surface and compute surface normal vectors for a real-time water simulation.
GPU programs were also written to improve the visual appearance of the surface of the water using reflection, refraction, bump mapping, and per-pixel lighting techniques.

 Graphics Processing Unit (GPU)
The technical definition of a GPU is "a single chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that is capable of processing a minimum of 10 million polygons per second."
With the advent of the GPU, computationally intensive transform and lighting calculations were offloaded from the CPU onto the GPU—allowing for faster graphics processing speeds.
The difficulty in virtual representations of the real world is robustly mimicking how objects interact with one another and their surroundings, due to the intense, split-second computations needed to process all the variables.

 S&TR | November 2005: Built for Speed: Graphics Processors for General-Purpose Computing
The use of graphics processing units (inset) for real-time georegistration of high-resolution wide-area imaging was demonstrated by Livermore’s Sonoma project.
Graphics processing on remote-collection platforms, such as in the one in this aircraft, reduces the volume of data transferred to users, enabling real-time analysis.
Because the tasks performed on a GPU occur in an order that is not controlled by a programmer, no one task can depend on the results of a previous one, and tasks cannot write to the same memory.

 PC World - How It Works: Graphics Boards   (Site not responding. Last check: 2007-10-15)
Graphics Board: A system component, usually an expansion card, that produces 2D or 3D images on a CRT monitor.
In response, the graphics driver--software that acts as a go-between for the OS and the graphics board--listens to the instructions from either the OS or the application, then takes the digital data and converts it into a format that the graphics board can understand.
The volume of pixels produced by the board is enormous: When your screen resolution is set to 1024 by 768, the graphics board calculates the precise color for, and produces, data for 786,432 pixels to draw the screen---and it repeats this process 30 to 90 times each second.

 Intel Looking Forward "High Performance Graphics" Engineers - GameDev.Net Discussion Forums   (Site not responding. Last check: 2007-10-15)
Integrating the GPU with the CPU is assinine unless the CPU would be able to make use of the GPU side for computation.
A CPU/GPU combo with a broken GPU is useless (maybe these/disbled GPU units could be sold cheaper) 6)eliminating the external bus from the performance equation would not grant any big performance benefits since graphics is largely a coputation-bound problem.
Also, the GPU *might* be able to share parts with the CPU such as branch prediction, registers, and floating-point units (this is an even bigger maybe) to help with the limited real-estate (which again could hurt CPU perforance).

 Overclocking your Graphics card for Newbies
All modern graphics cards have a Graphics Processing Unit (GPU) chip which performs graphics calculations, and memory which the GPU uses to perform these calculations.
The performance of a graphics card can be boosted by increasing the clockspeeds beyond the manufacturer's default settings.
All modern graphics cards use DDR (double data rate) memory, which explains why some people may refer to the same memory speed as 350MHz or 700MHz.

 Nvidia Demonstrates 256-Bit 'GPU' - Technology News by TechWeb
The chip also separates the geometry, lighting, setup, and rendering engines, typically processing one to three triangles at a time, up to a maximum of six.
Typically, graphics chips apply a lighting map to an object, which simulates but does not realistically calculate the path of light as it bounces off objects.
The net result is that in some applications, detail increases as the viewpoint zooms in -- exactly the opposite effect of what is usually found as zooming turns the object into a mass of discolored pixels.
