IBM 8514 is an IBM graphics computer display standard supporting a display resolution of 1024x768 pixels with 256 colors at 43.5 Hz (interlaced), or 640x480 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.
8514 used a standardised programming interface called the "Adapter Interface" or AI. This interface is also used by XGA, IBM 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).
8514 was introduced with the IBM Personal System/2 computers in April 1987. It was an optional upgrade to the Micro Channel architecture based PS/2's Video Graphics Array (VGA), and was delivered within three months of PS/2's introduction.
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 the TARGA Truevision series) were designed around special CPU or digital signal processor (DSP) chips, which were programmable. Fixed-function accelerators, such as the 8514, sacrificed programmability for better cost/performance ratio.
8514 was later superseded by IBM XGA.
Software that supported this graphic standard:
Third-party graphics suppliers did not clone IBM's 8514 as extensively as VGA.
