The TMS9918 is a video display controller (VDC) manufactured by Texas Instruments, in manuals referenced as "Video Display Processor" (VDP) and introduced in 1979.[1] The TMS9918 and its variants were used in the ColecoVision, CreatiVision, Memotech MTX, MSX, NABU Personal Computer, SG-1000/SC-3000, Spectravideo SV-318, SV-328, Sord M5, Tatung Einstein, TI-99/4, Casio PV-2000, Coleco Adam, Hanimex Pencil II, and Tomy Tutor.
The TMS9918 generates both grid-based character graphics (used to display text or background images) and sprites used for moving foreground objects.
The key features of this chip are, as highlighted on a 1980 presentation by Karl Guttag (one of the designers):[1]
256 by 192 full color pixels per screen
15 different colors and/or shades
Non-interlaced color composite video output
Direct wiring to RAS/CAS type dynamic RAMs
Automatic refresh of dynamic RAMs
General 8-bit memory mapped type CPU interface
CPU accesses RAM via VDP (no need for DMA)
32 dynamic characters per screen
Thirty-two 8×8 patterns per row, 24 rows per screen
Text mode with forty 6×8 patterns per row
Multicolor mode with 64 by 48 memory mappable color squares
