Oak Technologies
Oak Technology (OAKT) was an American supplier of semiconductor chips for sound cards, graphics cards and optical storage devices such as CD-ROM, CD-RW and DVD. It achieved success with optical storage chips and its stock price increased substantially around the time of the tech bubble in 2000. After falling on hard times, in 2003 it was acquired by Zoran Corporation. Oak Technology helped develop the ATAPI standard and provided the ''oakcdrom.sys'' CD-ROM driver that was ubiquitous on DOS-based systems in the mid-1990s. History Oak Technology, Inc. was founded by semiconductor pioneer David Tsang in 1987 and was headquartered in Sunnyvale, California, United States with operations across the US and Asia Pacific. During the late 1980s through the early 1990s, Oak was a supplier of PC graphics (SVGA) chipsets, CD-ROM controller chips and PCBs. Oak Technology also supplied motherboard chipsets – a PS/2-compatible chipset and the Oaknote chipset for notebooks. Oak enjoyed mode ...

Translucency
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are much larger than the wavelengths of the photons in question), the photons can be said to follow Snell's law. Translucency (also called translucence or translucidity) is the physical property of allowing light to pass through the material (with or without scattering of light). It allows light to pass through but the light does not necessarily follow Snell's law on the macroscopic scale; the photons may be scattered at either of the two interfaces, or internally, where there is a change in the index of refraction. In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. Transparent materials appear clear, with th ...

Sub-pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position. Software on ear ...

Floating Point
In computing, floating-point arithmetic (FP) is arithmetic on subsets of real numbers formed by a ''significand'' (a signed sequence of a fixed number of digits in some base) multiplied by an integer power of that base. Numbers of this form are called floating-point numbers. For example, the number 2469/200 is a floating-point number in base ten with five digits: 2469/200 = 12.345 = \! \underbrace_\text \! \times \! \underbrace_\text\!\!\!\!\!\!\!\overbrace^ However, 7716/625 = 12.3456 is not a floating-point number in base ten with five digits—it needs six digits. The nearest floating-point number with only five digits is 12.346. And 1/3 = 0.3333… is not a floating-point number in base ten with any finite number of digits. In practice, most floating-point systems use base two, though base ten (decimal floating point) is also common. Floating-point arithmetic operations, such as addition and division, approximate the corresponding real number arithmetic operations ...

Spatial Anti-aliasing
In digital signal processing, spatial anti-aliasing is a technique for minimizing the distortion artifacts (aliasing) when representing a high-resolution image at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other applications. Anti-aliasing means removing signal components that have a higher frequency than is able to be properly resolved by the recording (or sampling) device. This removal is done before (re)sampling at a lower resolution. When sampling is performed without removing this part of the signal, it causes undesirable artifacts such as black-and-white noise. In signal acquisition and audio, anti-aliasing is often done using an analog anti-aliasing filter to remove the out-of-band component of the input signal prior to sampling with an analog-to-digital converter. In digital photography, optical anti-aliasing filters made of birefringent materials smooth the signal in the spatial optical domain. The anti-a ...

Microsoft Talisman
Talisman was a Microsoft project to build a new 3D graphics architecture based on quickly compositing 2D "sub-images" onto the screen, an adaptation of tiled rendering. In theory, this approach would dramatically reduce the amount of memory bandwidth required for 3D games and thereby lead to lower-cost graphics accelerators. The project took place during the introduction of the first high-performance 3D accelerators, and these quickly surpassed Talisman in both performance and price. No Talisman-based systems were ever released commercially, and the project was eventually cancelled in the late 1990s. Description Conventional 3D Creating a 3D image for display consists of a series of steps. First, the objects to be displayed are loaded up into memory from individual ''models''. The display system then applies mathematical functions to transform the models into a common coordinate system, the ''world view''. From this world view, a series of polygons (typically triangles) is created t ...

Pin-compatibility
In electronics, pin-compatible devices are electronic components, generally integrated circuits or expansion cards, sharing a common footprint and with the same functions assigned or usable on the same pins. Pin compatibility is a property desired by systems integrators as it allows a product to be updated without redesigning printed circuit boards, which can reduce costs and decrease time to market. Although devices which are pin-compatible share a common footprint, they are not necessarily electrically or thermally compatible. As a result, manufacturers often specify devices as being either ''pin-to-pin'' or ''drop-in'' compatible. Pin-compatible devices are generally produced to allow upgrading within a single product line, to allow end-of-life devices to be replaced with newer equivalents, or to compete with the equivalent products of other manufacturers. Pin-to-pin compatibility ''Pin-to-pin compatible'' devices share an assignment of functions to pins, but may have dif ...

ViRGE
A virge or verge () is a type of rod, made of wood. Etymology Originally it was one or more branches (the French often use ''verges'', the plural of its equivalent, as the normal word for a rod, the rarer singular ''verge'' rather indicates a switch) used as an instrument for corporal punishment, or as a riding crop. It later became a symbol of civil office, used in ceremonies of swearing fealty (from which the legal term ''tenant by the verge'' is derived). Further deriving from this use is the sense of a measurement, and so boundary or border, of land, or generally a margin of space. Modern practice In modern times it is best known as the ceremonial staff of the Anglican and Episcopal lay church officers known as vergers (or originally ''virger'' – the title derives from ''virge''), who originally used it as a 'weapon' to make way for the ecclesiastical procession (compare the Catholic Swiss Guard The Pontifical Swiss Guard,; ; ; ; , %5BCorps of the Pontifical Swis ...

S3 Graphics
S3 Graphics, Ltd. was an American computer graphics company. The company sold the S3 Trio, Trio, S3 ViRGE, ViRGE, S3 Savage, Savage, and S3 Chrome, Chrome series of graphics processors. Struggling against competition from 3dfx Interactive, ATI Technologies, ATI and Nvidia, it merged with hardware manufacturer Diamond Multimedia in 1999. The resulting company renamed itself to SONICblue Incorporated, and, two years later, the graphics portion was spun off into a new joint effort with VIA Technologies. The new company focused on the mobile graphics market. VIA Technologies' stake in S3 Graphics was purchased by HTC in 2011. History S3 was founded and incorporated in January 1989 by Dado Banatao and Ronald Yara. It was named S3 as it was Banatao's third startup company. The company's first products were among the earliest graphical user interface (GUI) accelerators. These chips were popular with video card manufacturers, and their followup designs, including the S3 Trio, Trio64, ...

PowerVR
PowerVR is a division of Imagination Technologies (formerly VideoLogic) that develops hardware and software for 2D and 3D rendering, and for video encoding, video decoding, decoding, associated image processing and DirectX, OpenGL ES, OpenVG, and OpenCL acceleration. PowerVR also develops AI accelerators called Neural Network Accelerator (NNA). The PowerVR product line was originally introduced to compete in the desktop PC market for Graphics card, 3D hardware accelerators with a product with a better price–performance ratio than existing products like those from 3dfx Interactive. Rapid changes in that market, notably with the introduction of OpenGL and Direct3D, led to rapid consolidation. PowerVR introduced new versions with low-power electronics that were aimed at the laptop computer market. Over time, this developed into a series of designs that could be incorporated into system-on-a-chip architectures suitable for handheld device use. PowerVR accelerators are not manufactur ...

Graphics Accelerator
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 scanned out o ...
