■ Outline

YGV629 (Function name: VC1, hereinafter described as VC1) is a VDP (Video Display Processor), which

has a pattern rendering function by the sprite method according to the attribute settings and a direct line

rendering function. Since various effect functions are included sufficiently in the sprite function and line

rendering function, more effective presentation can be realized.

Since VC1 can display the bit map image with free display resolution, NTSC to SVGA, on any screen size

of monitor, OSD display control for various display units can be made.

And, VC1 includes a line buffer as a VRAM, so the system can be built with a little part. In addition,

pattern memory can be connected directly, so that the amount of the control program can be reduced.
