TeraScale (microarchitecture)
TeraScale is the codename for a family of graphics processing unit microarchitectures developed by ATI Technologies/AMD and their second microarchitecture implementing the unified shader model following '' Xenos''. TeraScale replaced the old fixed-pipeline microarchitectures and competed directly with Nvidia's first unified shader microarchitecture named Tesla. TeraScale was used in Radeon HD 2000 manufactured in 80 nm and 65 nm, Radeon HD 3000 manufactured in 65 nm and 55 nm, Radeon HD 4000 manufactured in 55 nm and 40 nm, Radeon HD 5000 and Radeon HD 6000 manufactured in 40 nm. TeraScale was also used in the AMD Accelerated Processing Units code-named "Brazos", "Llano", "Trinity" and "Richland". TeraScale is even found in some of the succeeding graphics cards brands. TeraScale is a VLIW SIMD architecture, while Tesla is a RISC SIMD architecture, similar to TeraScale's successor Graphics Core Next. TeraScale implements HyperZ. An LL ...

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 ...

Single Instruction, Multiple Data
Single instruction, multiple data (SIMD) is a type of parallel computer, parallel processing in Flynn's taxonomy. SIMD describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA. Such machines exploit Data parallelism, data level parallelism, but not Concurrent computing, concurrency: there are simultaneous (parallel) computations, but each unit performs exactly the same instruction at any given moment (just with different data). A simple example is to add many pairs of numbers together, all of the SIMD units are performing an addition, but each one has different pairs of values to add. SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern Cen ...

Free And Open-source Graphics Device Driver
A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. They may also control output to the display if the display driver is part of the graphics hardware. Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware. Drivers without freely (and legally) -available source code are commonly known as ''binary drivers''. Binary drivers used in the context of operating systems that are prone to ongoing development and change (such as Linux) create problems for end users an ...

FOSDEM
Free and Open source Software Developers' European Meeting (FOSDEM) is an annual software engineering conference. It is non-commercial and volunteer-organized with a focus on free and open-source software. Initiated in 2000, it is usually held during the first weekend of February, at the of the Université Libre de Bruxelles (ULB) in the southeast of Brussels, Brussels, Belgium. History FOSDEM was started in 2000 under the name Open Source Developers of Europe Meeting (OSDEM) by Raphael Bauduin. Bauduin said that since he felt he lacked the brains to properly contribute to the open-source community, he wanted to contribute by launching a European event in Brussels. Bauduin teamed up with Damien Sandras. The team repeated the event. The F (of FOSDEM) was added at the request of Richard Stallman. The Free Software Foundation's ceremony for the Award for the Advancement of Free Software was held at FOSDEM from 2002 to 2006 (for the awards for 2001 to 2005). The event has be ...

SIGGRAPH
SIGGRAPH (Special Interest Group on Computer Graphics and Interactive Techniques) is an annual conference centered around computer graphics organized by ACM, starting in 1974 in Boulder, CO. The main conference has always been held in North America; SIGGRAPH Asia, a second conference held annually, has been held since 2008 in countries throughout Asia. Overview The conference incorporates both academic presentations as well as an industry trade show. Other events at the conference include educational courses and panel discussions on recent topics in computer graphics and interactive techniques. SIGGRAPH Proceedings The SIGGRAPH conference proceedings, which are published in the ACM Transactions on Graphics, has one of the highest impact factors among academic publications in the field of computer graphics. The paper acceptance rate for SIGGRAPH has historically been between 17% and 29%, with the average acceptance rate between 2015 and 2019 of 27%. The submitted papers are ...

Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct successor to Windows 2000 for high-end and business users and Windows Me for home users. Development of Windows XP began in the late 1990s under the codename "Windows Neptune, Neptune", built on the Architecture of Windows NT#Kernel, Windows NT kernel and explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel or MS-DOS. Upon its release, Windows XP received critical acclaim, noting increased performance and stability (especially compared to Wi ...

Mesa (computer Graphics)
Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open source implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers. Its most important users are two graphics drivers mostly developed and funded by Intel and AMD for their respective hardware (AMD promotes their Mesa drivers Radeon and RadeonSI over the deprecated AMD Catalyst, and Intel has only supported the Mesa driver). Proprietary graphics drivers (e.g., Nvidia GeForce driver and Catalyst) replace all of Mesa, providing their own implementation of a graphics API. An open-source effort to write a Mesa Nvidia driver called Nouveau is developed mostly by the community. Besides 3D applications such as games, modern display servers ( X.org's Glamor or Wayland's Weston) use OpenGL/ EGL; therefore all graphics typically go through Mesa. Mesa is hosted by freedesktop.org and was initiated in August 1993 by Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
