Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles. GPUs were later found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure. The ability of GPUs to rapidly perform vast numbers of calculations has led to their adoption in diverse fields including artificial intelligence (AI) where they excel at handling data-intensive and computationally demanding tasks. Other non-graphical uses include the training of neural networks and cryptocurrency mining. History 1970s Arcade system boards have used specialized graphics circuits since the 1970s. In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scann ...

Application Programming Interface
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software Interface (computing), interface, offering a service to other pieces of software. A document or standard that describes how to build such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

Unified Video Decoder
Unified Video Decoder (UVD, previously called Universal Video Decoder) is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1. UVD was introduced with the Radeon HD 2000 Series and is integrated into some of AMD's GPUs and APUs. UVD occupies a considerable amount of the die surface at the time of its introduction and is not to be confused with AMD's Video Coding Engine (VCE). As of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN). Overview The UVD is based on an ATI Xilleon video processor, which is incorporated onto the same die as the GPU and is part of the ATI Avivo HD for hardware video decoding, along with the Advanced Video Processor (AVP). UVD, as stated by AMD, handles decoding of H.264/AVC, and VC-1 video codecs entirely in hardware. The UVD technology is based on the Cadence Tensilica Xtensa processor, which was originall ...

ATI Avivo
ATI Avivo is a set of hardware and low level software features present on the ATI Radeon R520 family of GPUs and all later ATI Radeon products. ATI Avivo was designed to offload video decoding, encoding, and post-processing from a computer's CPU to a compatible GPU. ATI Avivo compatible GPUs have lower CPU usage when a player and decoder software that support ATI Avivo is used. ATI Avivo has been long superseded by Unified Video Decoder (UVD) and Video Coding Engine (VCE). Background The GPU wars between ATI and NVIDIA have resulted in GPUs with ever-increasing processing power since early 2000s. To parallel this increase in speed and power, both GPU makers needed to increase video quality as well, in 3D graphics applications the focus in increasing quality has mainly fallen on anti-aliasing and anisotropic filtering. However it has dawned upon both companies that video quality on the PC would need improvement as well and the current APIs provided by both companies have n ...

Radeon X1000 Series
The R520 (codenamed Fudo) is a graphics processing unit (GPU) developed by ATI Technologies and produced by TSMC. It was the first GPU produced using a 90 nm photolithography process. The R520 is the foundation for a line of DirectX 9.0c and OpenGL 2.0 3D accelerator X1000 video cards. It is ATI's first major architectural overhaul since the R300 and is highly optimized for Shader Model 3.0. The Radeon X1000 series using the core was introduced on October 5, 2005, and competed primarily against Nvidia's GeForce 7 series. ATI released the successor to the R500 series with the R600 series on May 14, 2007. ATI does not provide official support for any X1000 series cards for Windows 8 or Windows 10; the last AMD Catalyst for this generation is the 10.2 from 2010 up to Windows 7.

DXVA
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU-intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU. DXVA 2.0 allows more operations, including video capturing and processing operations, to be hardware-accelerated as well. DXVA works in conjunction with the video rendering model used by the video card. DXVA 1.0, which was introduced as a standardized API with Windows 2000 ( DirectX 7), and is currently available on Windows 98 or later, can use either the overlay rendering mode or VMR 7/9. DXVA 2.0, available only on Windows Vista, Windows 7, Windows 8 and later OSs, integrates with Media Foundation (MF) and uses the Enhanced Video Renderer (EVR) present in MF. Overview The DXVA is used by software video decoders to define a codec-specific pipeline for hardware-accelerated d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Shader
Video Shader is a graphics card feature that ATI advertises on their R300 and R400 cards. The R500 card is advertised as having Video Shader HD. Video shader is a feature that describes ATI's process of using Pixel Shaders to improve quality of video playback. It can also be used to perform post-processing, like adding a film grain, or adding other special effects. One feature of Video Shader is ATI Full Stream. Full Stream detects the edges of video compression blocks and uses a pixel shader based filter to smooth the picture hiding the blocks. Another is Video Soap, which reduces video noise. Other features are DXVA support for Hardware Motion Compensation, iDCT, DCT and color space conversion. Support for Hardware Motion Compensation, iDCT, DCT and color space conversion is also listed. Video Shader has been superseded by Unified Video Decoder (UVD) and Video Coding Engine (VCE). See also * Unified Video Decoder Unified Video Decoder (UVD, previously called Unive ...
