VC1D
Video Controller 1 with Video Decoder

■ Overview
YGV632 (hereafter referred to as “VC1D,” its function name) is the display controller which makes it easier to create a highly
colorful graphic image in a low-cost system configuration.
With a built-in digital video recorder, it is easy to build up a system of superimposing characters, lines or graphic icons (up to
65536 color expression) over CVBS signals (Composite Video Signals) from a CCD camera, etc. Although there is an LSI called
OSDC (OSD controller), which are occasionally used as a low-cost system for superimposing characters and simple graphics over
video signals, VC1D realizes impressively higher colorful picture expression under an equivalent control load to OSDC.
Particularly, since the sprite system is used for generating graphic planes, it is possible to represent moving images like animation
even in CPU control by serial port communication.
A pattern memory for storing bitmap picture data called “sprites” or font data is externally connectable to VC1D (up to 512
Mbits). For using a sprite data, the CPU just needs to specify a sprite stored beforehand in the patter memory by its pattern memory
address and specify the position coordinates of the sprite on the display plane; then, VC1D automatically loads the sprite data from
the pattern memory so as to superimpose it over input video for output.
VC1D does not need such cumbersome frame memory management as existing graphic controllers do, which contributes to
reducing man-hours for development of control programs.
