Re: nacl_helper

From Wikipedia, the free encyclopedia
<http://en.wikipedia.org/wiki/Graphics_processing_unit#mw-head>
<http://en.wikipedia.org/wiki/Graphics_processing_unit#p-search>
Not to be confused with Graphics card
<http://en.wikipedia.org/wiki/Graphics_card>.
"GPU" redirects here. For other uses, see GPU (disambiguation)
<http://en.wikipedia.org/wiki/GPU_(disambiguation)>.

A *graphics processing unit* (*GPU*), also occasionally called *visual
processing unit* (*VPU*), is a specialized electronic circuit
<http://en.wikipedia.org/wiki/Electronic_circuit>designed to rapidly
manipulate and alter memory to accelerate the creation of images in a frame
buffer <http://en.wikipedia.org/wiki/Frame_buffer> intended for output to a
display. GPUs are used in embedded systems
<http://en.wikipedia.org/wiki/Embedded_system>, mobile phones
<http://en.wikipedia.org/wiki/Mobile_phone>, personal computers
<http://en.wikipedia.org/wiki/Personal_computer>, workstations
<http://en.wikipedia.org/wiki/Workstation>, and game consoles
<http://en.wikipedia.org/wiki/Game_console>. Modern GPUs are very efficient
at manipulating computer graphics
<http://en.wikipedia.org/wiki/Computer_graphics> and image processing
<http://en.wikipedia.org/wiki/Image_processing>, and their highly parallel
structure makes them more effective than general-purpose CPUs
<http://en.wikipedia.org/wiki/Central_processing_unit> for algorithms
<http://en.wikipedia.org/wiki/Algorithm> where processing of large blocks
of data is done in parallel. In a personal computer, a GPU can be present
on a video card <http://en.wikipedia.org/wiki/Video_card>, or it can be on
the motherboard <http://en.wikipedia.org/wiki/Motherboard> or--in certain
CPUs--on the CPU die <http://en.wikipedia.org/wiki/Die_(integrated_circuit)>.

The term GPU was popularized by Nvidia <http://en.wikipedia.org/wiki/Nvidia> in
1999, who marketed the GeForce 256
<http://en.wikipedia.org/wiki/GeForce_256> as "the world's first 'GPU', or
Graphics Processing Unit, a single-chip processor with integrated transform,
lighting, triangle setup/clipping
<http://en.wikipedia.org/wiki/Transform,_clipping,_and_lighting>, and
rendering engines that are capable of processing a minimum of 10 million
polygons per second". Rival ATI Technologies
<http://en.wikipedia.org/wiki/ATI_Technologies> coined the term visual
processing unit or VPU with the release of the Radeon 9700
<http://en.wikipedia.org/wiki/R300> in 2002.

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
