Weitek
Weitek Corporation was an American chip-design company that originally focused on floating-point units for a number of commercial CPU designs. During the early to mid-1980s, Weitek designs could be found powering a number of high-end designs and parallel-processing supercomputers. Weitek started in 1981, when several Intel engineers left to form their own company. Weitek developed math coprocessors for several systems, including those based on the Motorola 68000 family, the 1064 and 1164, and for Intel-based i286 systems, the 1067. Intel's own FPU design for the i386 fell far behind in development, and Weitek delivered the 1167 for them. The Weitek 1167 Floating Point Coprocessor provided the combination of Weitek 1163, 1164 and 1165 chipset. Later upgrades to this design led to the 2167, 3167 and 4167. Weitek would later outfit FPUs to the early SPARC architecture such as the 3170 and 3172. Weitek FPUs had several differences compared to x87 offerings, lacking extended doubl ...

Diamond Multimedia
Diamond Multimedia is an American company that specializes in many forms of multimedia technology. They have produced graphics cards, motherboards, modems, sound cards and MP3 players, however the company began with the production of the TrackStar, a PC add-on card which emulated Apple II computers. They were one of the major players in the 2D and early 3D graphics card competition throughout the 1990s and early 2000s. Diamond Multimedia is a subsidiary of Tul Corporation. History The company was founded by Chong Moon Lee and H. H. Huh, who acted as the technical designer. Diamond Multimedia later merged with S3 Graphics, S3, Incorporated in 1999 after a long-time cooperative business arrangement, when S3 decided to expand their business from producing graphics chipsets to manufacturing retail graphics cards. The move paralleled the 1999 3dfx purchase of STB Systems, which changed 3dfx from a graphics chipset supplier to companies including Diamond, into a vertically-integrated ...

SPARCstation
The SPARCstation, SPARCserver and SPARCcenter product lines are a series of SPARC-based computer workstations and server (computing), servers in desktop, desk side (pedestal) and rack-based form factor configurations, that were developed and sold by Sun Microsystems. The first SPARCstation was the SPARCstation 1 (also known as the Sun 4/60), introduced in 1989. The series was very popular and introduced the Sun-4c architecture, a variant of the Sun-4 architecture previously introduced in the Sun 4/260. Thanks in part to the delay in the development of more modern processors from Motorola, the SPARCstation series was very successful across the entire industry. The last model bearing the SPARCstation name was the SPARCstation 4. The workstation series was replaced by the Sun Ultra series in 1995; the next Sun server generation was the Sun Enterprise line introduced in 1996. Models Desktop and deskside SPARCstations and SPARCservers of the same model number were essentially identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPARC
SPARC (Scalable Processor Architecture) is a reduced instruction set computer (RISC) instruction set architecture originally developed by Sun Microsystems. Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s. First developed in 1986 and released in 1987, SPARC was one of the most successful early commercial RISC systems, and its success led to the introduction of similar RISC designs from many vendors through the 1980s and 1990s. The first implementation of the original 32-bit architecture (SPARC V7) was used in Sun's Sun-4 computer workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 series of processors. SPARC V8 added a number of improvements that were part of the SuperSPARC series of processors released in 1992. SPARC V9, released in 1993, introduced a 64-bit architecture and was first released in Sun's UltraSPARC processors in 1995. Later, SPARC processors were used in symm ...

Laser Printer
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively-charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically-charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum. Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frame Buffer
A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. Modern video cards contain framebuffer circuitry in their cores. This circuitry converts an in-memory bitmap into a video signal that can be displayed on a computer monitor. In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. Screen buffers should be distinguished from video memory. To this end, the term off-screen buffer is also used. The information in the buffer typically consists of color values for every pixel to be shown on the display. Color values are commonly stored in 1-bit binary (monochrome), 4-bit palettized, 8-bit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Microsystems
Sun Microsystems, Inc. (Sun for short) was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC microprocessors.

Workstation
A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-user operating systems. The term ''workstation'' has been used loosely to refer to everything from a mainframe computer terminal to a PC connected to a network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems, Silicon Graphics, Apollo Computer, DEC, HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s. Workstations offer higher performance than mainstream personal computers, especially in CPU, graphics, memory, and multitasking. Workstations are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like computational fluid dynamics, animation, medical imaging, image rendering, and ...

VESA Local Bus
The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced during the i486 generation of x86 IBM-compatible personal computers. Created by VESA (Video Electronics Standards Association), the VESA Local Bus worked alongside the then-dominant ISA bus to provide a standardized high-speed conduit intended primarily to accelerate video (graphics) operations. VLB provides a standardized fast path that add-in (video) card makers could tap for greatly accelerated memory-mapped I/O and DMA, while still using the familiar ISA bus to handle basic device duties such as interrupts and port-mapped I/O. Some high-end 386dx motherboards also had a VL-Bus slot. Historical overview In the early 1990s, the I/O bandwidth of the prevailing ISA bus, 8.33 MB/s for standard 16 bit 8.33 MHz slots, had become a critical bottleneck to PC video and graphics performance. The need for faster graphics was driven by increased adoption of graphical user interfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SVGA
Super VGA (SVGA) is a broad term that covers a wide range of computer display standards that extended IBM's VGA Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the PC industry within three years. The term can no ... specification. When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800×600. History In the late 1980s, after the release of IBM's VGA, third-party manufacturers began making graphics cards based on its specifications with extended capabilities. As these cards grew in popularity they began to be referred to as "Super VGA." This term was not an official standard, but a shorthand for enhanced VGA cards which had become common by 1988. One card that explicitly used the term was Genoa's SuperVGA HiRes. Super VGA cards broke compatibility with the IBM VGA standard, requiring sof ...
