Cable
Software|
-Program_Debug_v12.2_win.exe| This executable file installs FlashPro Express, used to program the FPGA.

Prerequisites

Before you start:

1. Download the programming job file from:
   http://soc.microsemi.com/download/rsc/?f=mpf_dg0889_liberosoc_jb

2. Download and install the GUI from:
   http://soc.microsemi.com/download/rsc/?f=mpf_dg0849_liberosoc_gui

3. Download and install the Program and Debug software from:
   http://soc.microsemi.com/download/reg/download.aspxp=f=ProgramDebug_v12_2_WIN

Note: On this web page, download the Program_Debug_v12.2_win.exe binary file. Installation of this executable file installs FlashPro Express used for FPGA programming. FlashPro Express is used in this demo.

Note: The Program and Debug Software also installs the drivers on the host PC to detect the COM port for running the demo. Install this software whenever the demo is run on a different host PC.

Demo Resources
The mpf_dg0889_liberosoc_jb folder contains the following resources:

• A job file (JOB file): This file includes the FPGA bitstream and the SPI Flash image to be programmed.

For programming the FPGA using the job file, see Programming the PolarFire Device, page 8.

Demo Design
The following block diagram shows the SDI demo design implemented in the PolarFire FPGA using Libero SoC.

**Figure 2 • Top-Level Block Diagram

**

The following points summarize the data flow in the design:

• The demo uses a dual camera module that captures the real-time video data. This video data is received by the PolarFire FPGA via the MIPI-CSI2 RX interface on the board.
• The real-time video data is converted to the YCbCr 422 format by an Image Signal Processing (ISP) IP and stored in the DDR memory as frame buffer.
• The SDI TX IP fetches these frames and transmits the data at 12G using PolarFire Transceiver (XCVR). The 12G-SDI data is looped back via the BNC cable on the SDI daughter card and received at the receive end of the XCVR.
• The SDI RX IP receives the data and stores the frame buffer in the DDR memory  in a different address space. Finally, the received data is fetched by the HDMI 2.0 IP and displayed on a HDMI monitor.

The PolarFire 12G-SDI Libero design is available at http://soc.microsemi.com/download/rsc/?f=mpf_dg0889_liberosoc_df.

The Libero project must be opened using Libero SoC v12.2. The Libero SoC v12.2 is available for download at
https://www.microsemi.com/product-directory/design- resources/1750liberosoc#downloads.

Clocking Structure

The clocks generated from the onboard oscillator are used in the demo design. Using the 27 MHz reference frequency from the onboard oscillator, PF_CCC_C0 generates a 40 MHz clock for the XCVR_ERM_C1 (SDI_RX), and a 50 MHz clock for the Mi-V processor subsystem and DDR Controller. Using the reference frequency of 200 MHz (DDR System clock), PF_CCC_C1 generates a 148.5 MHz clock for XCVR_ERM_C0 (HDMI) and Display Controller.

Using the 148.5 MHz onboard oscillator, PF_XCVR_REF_CLK generates the following clocks:

• 148.5 MHz clock (LANE0_TX_CLK_G) for the SDI User Logic.
  148.5 MHz clock (LANE0_RX_CLK_R) for the DDR Write Logic.

Using the reference frequency of 150 MHz, PF_CCC generates a 120 MHz clock for

MIPI_RX_DECODER. Figure 3, page 5 shows the clocking structure of the design.

**Figure 3 • Clocking Structure

**

Reset Structure
The Mi-V processor subsystem, XCVR, UART, SDI, ISP, and all other blocks are reset when the following signals are asserted:

• DEVICE_INIT_DONE from PF_INIT_MONITOR
• DDR_CTRL_RDY from DDR Controller
• DDR PLL_LOCK
• PLL_LOCK of PF_CCC_C0

The reset structure is shown in Figure 4, page 6

**Figure 4 • Reset Structure

   **Figure 8 • Programming the Device

**

6. Click RUN to program the device. When the device is programmed successfully, a RUN PASSED status is displayed as shown in Figure 5, page 7. See Running the Demo, page 8.
   **Figure 9 • FlashPro Express-RUN PASSED

**  Close FlashPro Express (Project > Exit). The PolarFire device and SPI Flash are programmed. Power cycle the board using switch SW4. After power cycling, the HDMI monitor displays the live video from camera.

Running the Demo

The demo features receiving the MIPI Rx data from the IMX334 camera with 4K resolution at 30 frames per second (fps). The frames from camera are converted to YCbCr 422 format and stored in DDR.The 12G SDI Tx IP transmits the DDR video frames using PolarFire XCVR. The 12G SDI Rx IP receives the SDI video and stores the frames in DDR. The HDMI IP reads the frame buffer written by SDI Rx IP and sends out to HDMI display using XCVR. The image processing IPs are enabled on the display side of the video pipeline.

In the demo design, two display controllers are used to provide two video outputs:

1. Start the Video_Control GUI from the installation directory. The GUI is displayed as shown in the following figure.
   Figure 10 • Video_Contol GUI
   

2. Select the second largest COM port on the GUI and select the Connect option.
   Figure 11 • Connecting the GUI and Video kit
   

3. The Connect button turns green indicating a successful connection.
   **Figure 12 • Connection Successful

**

4. Use the Contrast and Brightness sliders to adjust the contrast and brightness and observe the change on the HDMI monitor. The sliders are highlighted in the following figure.
   Figure 13 • Adjusting Contrast and Brightness |

5. Similarly, adjust the color balance of the image using the color balance sliders.

6. In the main video control GUI window, select the Panning option to view a particular area of the main or the PIP image within a 4K image.

7. In the Panning Menu, use Image Select to select the image to be panned (Main image or PIP image). Any area of the 4K camera feed can be viewed by dragging the pink box horizontally or vertically. The Reset option sets the view of the Main image and PIP image to its default center position.
   **Figure 14 • Panning Menu

**

8. Close the Panning Menu to return to the main GUI.
9.  Close the GUI to exit from the demo.

Note: The following features in the GUI are not supported in the current SDI design:

• Alpha
• Edge
• PIP

This concludes the demo.
