NationMaster - Encyclopedia: 8514 (display standard)

The 8514 is an IBM graphics computer display standard supporting a display resolution of 1024×768 pixels with 256 colours at 43.5 Hz (interlaced), or 640×480 at 60 Hz (non-interlaced). 8514 usually refers to the display controller hardware (such as the 8514/A display adapter.) However, IBM sold the companion CRT monitor (for use with the 8514/A) which carries the same designation, 8514. International Business Machines Corporation (IBM, or colloquially, Big Blue) (NYSE: IBM) (incorporated June 15, 1911, in operation since 1888) is headquartered in Armonk, New York, USA. The company manufactures and sells computer hardware, software, and services. ... It has been suggested that Display standard be merged into this article or section. ...

This example shows an image with a portion greatly enlarged, in which the individual pixels are rendered as little squares and can easily be seen. ... The hertz (symbol: Hz) is the SI unit of frequency. ... Interlacing is a method of displaying images on a raster-scanned display device, such as a cathode ray tube (CRT). ...

8514 used a standardised programming interface called the "Adapter Interface" or AI. This interface is also used by XGA, IBM's Image Adapter/A, and clones of the 8514/A and XGA such as the ATI Technologies Mach 32 and IIT AGX. The interface allows computer software to offload common 2D-drawing operations (line-draw, color-fill, BITBLT) onto the 8514 hardware. This freed the host CPU for other tasks, and greatly improved the speed of redrawing a graphics visual (such as a pie-chart or CAD-illustration). ATI Technologies Inc. ...

History

8514 was introduced at the same time as VGA (1987) Video Graphics Array (VGA) is a computer display standard first marketed in 1987 by IBM. VGA belongs to a family of earlier IBM video standards and largely remains backward compatible with them. ... 1987 (MCMLXXXVII) was a common year starting on Thursday of the Gregorian calendar. ...

Although not the first PC video card to support hardware acceleration, IBM's 8514 is often credited as the first PC mass-market fixed-function accelerator. Up until the 8514's introduction, PC graphics acceleration was relegated to expensive workstation-class, graphics coprocessor boards. Coprocessor-boards (such as IBM's PGC and the TARGA Truvision series) were designed around special CPU or DSP chips, which in theory could execute a compiled program. (IBM PGC used a variant of the Intel 8086 processor. At least 1 Truvision model used the Texas Instruments TMS34010.) Fixed-function accelerators, such as the 8514, sacrificed programmability for better cost/performance ratio. A video card, (also referred to as a graphics card, graphics accelerator card, display adapter and numerous other terms), is an item of personal computer hardware whose function is to generate and output images to a display. ... Professional Graphics Controller was an IBM XT graphics card manufactured by IBM. It was very advanced, providing both 2D and 3D graphics accelerator for CAD applications. ... Intel Corporation (NASDAQ: INTC, SEHK: 4335), founded in 1968 as Integrated Electronics Corporation, is an American multinational corporation that is best known for designing and manufacturing microprocessors and specialized integrated circuits. ... Texas Instruments (NYSE: TXN), better known in the electronics industry (and popularly) as TI, is an American company based in Dallas, Texas, USA, renowned for developing and commercializing semiconductor and computer technology. ...

8514 was later superseded by IBM XGA. XGA, the Extended Graphics Array, is an IBM display standard introduced in 1990. ...

Clone hardware

Third-party graphics suppliers did not clone IBM's 8514 as extensively as VGA. Nevertheless, ATI did develop 8514-compatible graphics controllers : the Mach8 and Mach32. Both were sold in ATI-branded graphics boards.
