ANTIC
Alphanumeric Television Interface Controller (ANTIC) is an LSI ASIC dedicated to generating 2D computer graphics to be shown on a television screen or computer display. Under the direction of Jay Miner, the chip was designed in 1977–1978 by Joe Decuir, Francois Michel, and Steve Smith for the Atari 8-bit computers first released in 1979. The chip was patented by Atari, Inc. in 1981. ANTIC is also used in the 1982 Atari 5200 video game console, which shares most of the same hardware as the 8-bit computers. For every frame of video, ANTIC reads instructions to define the playfield, or background graphics, then delivers a data stream to the companion CTIA or GTIA chip which adds color and overlays sprites (referred to as "Player/Missile graphics" by Atari). Each ANTIC instruction corresponds to either blank scan lines or one of 14 graphics modes used for a horizontal band of the display. The height of each band depends on the mode. The instructions comprise a display l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CTIA And GTIA
Color Television Interface Adaptor (CTIA) and its successor Graphic Television Interface Adaptor (GTIA) are custom chips used in the Atari 8-bit computers and Atari 5200 home video game console. In these systems, a CTIA or GTIA chip works together with ANTIC to produce the video display. ANTIC generates the playfield graphics (text and bitmap) while CTIA/GTIA provides the color for the playfield and adds overlay objects known as player/missile graphics (sprite (computer graphics), sprites). Under the direction of Jay Miner, the CTIA/GTIA chips were designed by George McLeod with the technical assistance of Steve Smith. ''Color Television Interface Adaptor'' and ''Graphic Television Interface Adaptor'' are names of the chips as stated in the Atari field service manual. Various publications named the chips differently, sometimes using the alternative spelling ''Adapter'' or ''Graphics'', or claiming that the "C" in "CTIA" stands for Atari 400, Colleen/Candy and "G" in "GTIA" is f ...

Atari 8-bit Computers
The Atari 8-bit computers, formally launched as the Atari Home Computer System, are a series of home computers introduced by Atari, Inc., in 1979 with the Atari 400 and Atari 800. The architecture is designed around the 8-bit MOS Technology 6502 CPU and three custom coprocessors which provide support for sprites, smooth multidirectional scrolling, four channels of audio, and other features. The graphics and sound are more advanced than most of its contemporaries, and video games are a key part of the software library. The 1980 first-person space combat simulator ''Star Raiders'' is considered the platform's killer app. The Atari 800 was positioned as a high-end model and the 400 as more affordable. The 400 has a pressure-sensitive, spillproof membrane keyboard and initially shipped with a non-upgradable of RAM. The 800 has a conventional keyboard, a second cartridge slot, and allows easy RAM upgrades to 48K. Both use identical 6502 CPUs at ( for PAL versions) and coprocess ...

Horizontal Blank Interrupt
A raster interrupt (also called a horizontal blank interrupt) is an interrupt signal in a legacy computer system which is used for display timing. It is usually, though not always, generated by a system's graphics chip as the scan lines of a frame are being readied to send to the monitor for display. The most basic implementation of a raster interrupt is the vertical blank interrupt. Such an interrupt provides a mechanism for graphics registers to be changed mid-frame, so they have different values above and below the interrupt point. This allows a single-color object such as the background or the screen border to have multiple horizontal color bands, for example. Or, for a hardware sprite to be repositioned to give the illusion that there are more sprites than a system supports. The limitation is that changes only affect the portion of the display below the interrupt. They don't allow more colors or more sprites on a single scan line. Modern protected mode operating systems ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari 5200
The Atari 5200 SuperSystem or simply Atari 5200 is a home video game console introduced in 1982 by Atari, Inc. as a higher-end complement for the popular Atari Video Computer System. The VCS was renamed to Atari 2600 at the time of the 5200's launch. Created to compete with Mattel's Intellivision, the 5200 wound up a direct competitor of ColecoVision shortly after its release. While the Coleco system shipped with the first home version of Nintendo's '' Donkey Kong'', the 5200 included the 1978 arcade game '' Super Breakout'', which had already appeared on previous Atari home platforms. The system architecture is almost identical to that of the Atari 8-bit computers, although software is not directly compatible between them. The 5200's controllers have an analog joystick and a numeric keypad along with start, pause, and reset buttons. The 360-degree non-centering joystick was touted as offering more control than the eight-way Atari CX40 joystick of the 2600, but it was a ...

Antic (magazine)
''Antic'' was a print magazine devoted to Atari 8-bit computers and later the Atari ST. It was named after the ANTIC chip in the 8-bit line which, in concert with CTIA or GTIA, generates the display. The magazine was published by Antic Publishing from April 1982 until June/July 1990.''Antic'' printed type-in programs (usually in Atari BASIC), reviews, and tutorials, among other articles. Each issue contained one type-in game as "Game of the Month." In 1986, ''STart'' magazine was spun off to exclusively cover the Atari ST line. Its main rival in the United States was '' ANALOG Computing'', another long-lived magazine devoted to the Atari 8-bit line. Multi-system magazines '' COMPUTE!'' and '' Family Computing'' also served Atari 8-bit owners with type-in programs. Starting in 1984, the catalog for Antic Software was bound into issues of ''Antic''. History NASA programmer Jim Capparell was an early Atari 8-bit computer owner. He quit his job on 15 January 1982 to found a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Display List
A display list, also called a command list in Direct3D 12 and a command buffer in Vulkan, is a series of graphics commands or instructions that are run when the list is executed. Systems that make use of display list functionality are called retained mode systems, while systems that do not are as opposed to immediate mode systems. In OpenGL, display lists are useful to redraw the same geometry or apply a set of state changes multiple times. This benefit is also used with Direct3D 12's bundle command lists. In Direct3D 12 and Vulkan, display lists are regularly used for per-frame recording and execution. Origins in vector displays The vector monitors or ''calligraphic displays'' of the 1960s and 1970s used electron beam deflection to draw line segments, points, and sometimes curves directly on a CRT screen. Because the image would immediately fade, it needed to be redrawn many times a second ( storage tube CRTs retained the image until blanked, but they were unsuitable for in ...

Sprite (computer Graphics)
In computer graphics, a sprite is a Plane (mathematics), two-dimensional bitmap that is integrated into a larger scene, most often in a 2D video game. Originally, the term ''sprite'' referred to fixed-sized objects composited together, by hardware, with a background. Use of the term has since become more general. Systems with hardware sprites include arcade video games of the 1970s and 1980s; game consoles including as the Atari VCS (1977), ColecoVision (1982), Nintendo Entertainment System, Famicom (1983), Sega Genesis, Genesis/Mega Drive (1988); and home computers such as the TI-99/4 (1979), Atari 8-bit computers (1979), Commodore 64 (1982), MSX (1983), Amiga (1985), and X68000 (1987). Hardware varies in the number of sprites supported, the size and colors of each sprite, and special effects such as scaling or reporting pixel-precise overlap. Hardware composition of sprites occurs as each scan line is prepared for the video output device, such as a cathode-ray tube, without i ...
