graphics accelerator
A display adapter that performs a specialized set of functions in hardware to render an image on screen. Today, all display adapters (graphics cards) provide basic rendering functions; however, most of them have graphics processing units (GPUs) that are actually programmable CPUs. They move an image through a parallel processing pipeline that performs a different graphics function simultaneously at each stage. For more details, see graphics pipeline and GPU.
(graphics, hardware)graphics accelerator - Hardware (often an extra circuit board) to perform tasks such as plotting lines and surfaces in two or three dimensions, filling, shading and hidden line removal.

Other subjects examined include performance evaluation in uniform interactive Markov chains, a fast rendering algorithm of underwater optical effects, 3D accelerator technology for games, target identification in the battlefield based on evidence theory, and a component analysis method for evaluating wireless mobile ad hoc network routing protocols.
TBR technology typically requires less than one third of the memory bandwidth required by conventional 3D accelerators, which allows content developers to focus on realistic environments rather than having to resort to programming tricks to reduce scene complexity and image quality, which are required to improve frame rate with traditional 3D accelerators.
The annual Microprocessor Forum, which will take place in San Jose early in October, promises disclosures of Intel Corp's Coppermine and Merced processors, further members of Advanced Micro Devices Inc's Athlon processor range, two new 3D accelerators, and "a radically new architecture for multimedia and networking applications.
