S3C6410硬件DISPLAY CONTROLLER(显示控制器)


1、OVERVIEW

LCD driver interface has four kinds of interface, i.e. the conventional RGB-interface, I80 Interface and  NTSC/PAL standard TV  Encoder Interface and IT-R BT. 601 interface. The DISPLAY controller supports up to 5 overlay image windows. Overlay image windows support various color format, 16 level alpha blending, color key, x-y position control, soft scrolling, variable window size, and etc.The DISPLAY controller supports various color formats such as RGB (1BPP to 24 BPP), and YCbCr 4:4:4(only local bus).

LCD 驱动接口有四种接口,如传统的RGB 接口,I80 接口,NTSC/PAL 标准TV 编码器接口和IT-R BT.601 接口。显示控制器支持5 层图像窗口。覆盖图像窗口支持多种颜色格式、16 级alpha 混合、color key,横纵坐标位置控制,软动,可变窗口尺寸等等。显示控制器支持各种颜色格式,如RGB(1BPPto24BPP),YcbCr4:4:4.

The DISPLAY controller is used to transfer the video data and to generate the necessary control signals such as,
RGB_VSYNC, RGB_HSYNC, RGB_VCLK, RGB_VDEN, and SYS_CS0(as well as the control signals). DISPLAY
controller has the data ports for video data, which are RGB_VD[23:0], SYS_VD[17:0], and TV_OUT as shown in
Figure 14-1.

显示控制器用来转换视频数据,并产生需要的控制信号,如,RGB_VSYNC, RGB_HSYNC, RGB_VCLK,
RGB_VDEN 和SYS-CS0(作为控制信号)。显示控制器有视频数据端口,这些数据端口是RGB_VD[23:0]和
SYS_VD[17:0],TV_OUT 如图14-1 所示。
