1 DISPLAY CONTROLLER
1.1 OVERVIEW OF DISPLAY CONTROLLER
The Display controller consists of logic for transferring image data from a local bus of the camera interface
controller or a video buffer located in system memory to an external LCD driver interface. The LCD driver interface
supports three kinds of interface, namely, RGB-interface, indirect-i80 interface, and YUV interface for writeback.
The display controller uses up to five overlay image windows that support various color formats, 256 level alpha
blending, color key, x-y position control, soft scrolling, and variable window size, among others.

该显示控制器包括用于将图像数据从相机接口的本地总线传输的逻辑

控制器或将在系统内存中的视频缓冲区设置为外部的液晶显示驱动程序接口。液晶驱动接口

支持三种接口，即RGB接口，indirect-i80接口，和写回YUV接口。

显示控制器使用多达五个覆盖图像窗口，支持各种颜色格式，256级阿尔法

混合，颜色键，X-Y位置控制，软滚动，和可变窗口大小，等等。

The display controller supports various color formats such as RGB (1 bpp to 24 bpp) and YCbCr 4:4:4 (only local

bus). It is programmed to support the different requirements on screen related to the number of horizontal and
vertical pixels, data line width for the data interface, interface timing, and refresh rate.

显示控制器支持多种颜色格式如RGB（1 BPP 24 BPP）和YCbCr 4:4:4（唯一的地方

总线）。它被编程，以支持屏幕上的不同要求的数量水平和

垂直像素，数据线宽度为数据接口，接口时序，刷新率。

The display controller transfers the video data and generates the necessary control signals, such as,

RGB_VSYNC, RGB_HSYNC, RGB_VCLK, RGB_VDEN and SYS_CS0, SYS_CS1, SYS_WE. In addition to
generating control signals, the display controller contains data ports for video data (RGB_VD[23:0], and SYS_VD),

as shown in Figure 1-1.

显示控制器传输视频数据，并产生必要的控制信号，例如，

rgb_vsync，rgb_hsync，rgb_vclk，rgb_vden和sys_cs0，sys_cs1，sys_we。除了

产生控制信号，显示控制器包含视频数据的数据端口（rgb_vd [23时]，和sys_vd），

如图1-1所示。

2CAMERA INTERFACE
2.1 OVERVIEW OF CAMERA INTERFACE
The camera interface (CAMIF) in S5PV210 is a fully interactive mobile camera interface. CAMIF supports ITU R
BT-601/656 standard, AXI interface and MIPI (CSI). The maximum input image size of CAMIF is 8192 x 8192
pixels.

相机接口（camif）在S5PV210是完全互动的移动摄像头接口。camif支持ITU R

bt-601 / 656标准，AXI接口和MIPI（CSI）。对camif最大输入图像尺寸是8192 x 8192

像素。

S5PV210 has three CAMIF units, namely, CAMIF0, CAMIF1 and CAMIF2, as shown in Figure 2-1.
Each of these units is designed to perform different functions, as shown inFigure 2-2.
• T_PatternMux generates test pattern to calibrate input sync signals as HREF and VSYNC.
• Capture specifies the capturing signal and window cut. Use the register settings to invert video sync signals
and pixel clock polarity in CAMIF.
• Scaler generates various sizes for an image.
• Input DMA (read only) reads from the memory image data.
• Output DMA (write only) writes image data to memory.
• CAMIF supports image rotation (90 degrees clockwise) and image effect functions.

camif S5PV210有三个单元，即camif0，camif1和camif2，如图2-1所示。

这些单位是设计来执行不同的功能，如图2-2所示。

•t_patternmux生成测试模式校准输入同步信号VSYNC href和。

捕获指定捕获信号和窗口切割。使用寄存器设置来反转视频同步信号

在camif像素时钟极性。

•Scaler的图像生成各种尺寸。

•输入DMA（只读）从内存中读取图像数据。

•输出DMA（只写）写图像数据的存储。

•camif支持图像旋转（顺时针旋转90度）和图像效果功能。

6MULTI FORMAT CODEC
6.1 INTRODUCTION
The multi-format video codec is a synthesizable core which can perform encoding and decoding of multiple
streams at 30fps up to 1080p resolution image (1920x1080).

多格式视频编解码器是一个合成的核心，可以进行编码和解码的多

30fps的1080p分辨率的图像流到（1920X1080）。

The MFC can handle a real-time coding up to 16 multi-channels which supports H.264, MPEG4, MPEG2, VC-1
and H.263. Detailed features are described in later sections. Note that MFC can support up to 16 channels, but
the actual number of channels is dependent on use cases and limited by many system specific factors, such as
the system memory, the clock speed provided to MFC, and so on.

MFC可以处理实时编码多达16多渠道支持H.264，MPEG4，MPEG2，VC-1，

与H.263。详细的功能在后面的章节中描述。注意，MFC可以支持多达16个频道，但

渠道的实际数量是依赖于使用的情况下，由许多系统特定的因素，如有限的

系统内存，提供了MFC的时钟速度，等等。
