Figure 4-11 shows the block diagram of the demonstration. The CMOS sensor's raw data will be written
in SDRAM first. After finishing writing a frame, Sdram_Control module will read out the data from
SDRAM to RAW2RGB_J module to convert RAW data to RGB data. The RGB data will output along
with the signal timing generated by VGA_Controller to the LCD. In this block, it also provides an
“auto-focusing” module, “monitor CMOS sensor frame rate” module, as well as a "pixel clock" module.
All module functions are described below:


MIPI_BRIDGE_CAMERA_Config: the MIPI BRIDGE I2C and Camera I2C setting controller,
such as set to output 800X480@60Hz timing. It mainly writes I2C corresponding parameters to
MIPI-BRIDGE IC register and Camera Sensor IC register respectively through their own I2C buses.
MIPI_I2C bus is used to write MIPI BRIDGE I2C (I2C Slave Address = 0x1c.), CAMERA_I2C
bus is used to write Camera Sensor (IC Slave Address = 0x6c).

Sdram_Control: This module is one Sdram_Controller can control general external SDRAM
Memory and read/write image data.

RAW2RGB_J: This module is to convert RAW data to RGB data.

VGA_Controller: the LCD signal timing generator, can generate signal timing which the resolution
is 800x480.

FOCUS_ADJ: This module provides two main functions.
