Video display controller
A video display controller or VDC is an integrated circuit which is the main component in a video signal generator, a device responsible for the production of a TV video signal in a computing or game system. Some VDCs also generate an audio signal, but in that case it is not their main function.
List of example VDCs[edit | edit source]
- The Fujitsu MB14241 was used to accelerate the drawing of sprite graphics for various 1970s arcade games from Taito and Midway, such as Gun Fight (1975), Sea Wolf (1976) and Space Invaders (1978). Using a frame buffer system, it was capable of displaying up to 60 sprites on screen, and move up to 24 of them at once.
- The Sega Master System uses an enhanced VDP based on the TMS9918, and the Sega 315-5313 (Yamaha YM7101) VDP used in the Sega Mega Drive and some arcade machines is a further advancement of the Master System VDP with the original (inferior) TMS9918 modes removed.
- The Yamaha V9938 is an improved version of the TMS9918, and was mainly used in the MSX2.
- The Yamaha V9958 is the Video Display Processor (VDP) mainly used in the MSX2+ and MSX turboR computers.
