Video Controller 1 with Enhanced Functions
■ Outline
YGV639 (hereafter referred to as “VC1E,” its function name) is the display controller which makes it
easier to create a highly colorful graphic image in a low-cost system configuration.
VC1E, having a build-in digital video decode, allows characters, lines, and graphic icons (hereafter, called
“sprite”) to be superimposed over CVBS signal from a CCD camera.
It is possible to represent moving images like animation even through a serial port communication, and
VC1E realize impressively higher colorful picture expression under an equivalent CPU control load as that of
a low-cost OSD controller.
A pattern memory, up to 512M bits (64M bytes), for storing font data or bitmap display data that are used
for a sprite, is connectable to VC1E.
A complicated display control program needed to be developed for the conventional graphic controller;
however, VC1E allows sprites to be easily displayed only by rewriting the attribute table for display.
VC1E has a build-in line memory for display. For this reason, an external VRAM becomes unnecessary
and this allows a system to be built with fewer components.
With recent increase of safety awareness, in-vehicle video cameras are becoming more and more popular.
VC1E is best suited for such as parking-support system as would perform superimposition of car-width lines
over a video camera footage.
VC1E measures up to the in-vehicle temperature guarantee conditions and can be used also for in-vehicle
ECU.
