Part 3: HDMI DEMO program description
We provide an HDMI loop test routine for the ALINX FPGA development board, in
which the video image of the HDMI input is looped directly to the HDMI output
image. In addition, the register configuration and EDID information of the
SiI9013 and SiI9134 chips are generated in the program.
EDID describes the display information and is an important part of the video
system, indicating the format supported by the HDMI Receiver section of the
HDMI module. The general EDID is the I2C interface, and the information is
stored in the EEPROM. However, in this design, the EDID information is stored
in the FPGA chip and implemented by the program. The external master device
can access the EDID information of the HDMI module through I2C. 
Figure 3-1: FPGA loop test
Here’s a brief introduction to the various modules used in the FPGA program:
-
hdmi_loop.v
TOP program module, instantiate several sub-modules, and perform 2-level latching on the video signal of HDMI input -
i2c_config.v
This module configured the register of the SiI9134 chip and SiI9013 by calling the I2C communication module. The configured register address and value are defined in the lut_data register. The specific register meanings refer to the chip manuals of SiI9134 and SiI9013. -
i2c_config.v
Power-on reset module, after power-on, generates a software reset to initialize other modules -
EEPROM_8b.v
The EDID slave device of the analog EEPROM, the external display master device can read the EDID information through the I2C bus. An EEPROM register is defined in the program for storing the EDID information. The EDID information is initialized by reading the .txt file when the power is turned on. Users can modify different .EDED.txt files to achieve different video input formats. By default, we choose to support 1080P input format.
Part 4: Hardware connection and testing
The hardware connection between the FL9134 module and the FPGA development
board is very simple. Simply plug the FL0214 FMC interface into the FMC
interface of the FPGA development board and fix it with screws. The following
is the hardware connection diagram of the ALINX AX7350 development board and
FL9134 
After the FPGA development board is powered on, the download program can display the computer output or the video image of the set-top box on the HDMI display (in the experiment, the HDMI input is connected to the video output of the set-top box, so the HDMI display shows the video image output by the set-top box) .
