2.2 Prerequisites

Before you start:

1. Download the programming job file from:
   http://soc.microsemi.com/download/rsc/?f=mpf_dg0849_liberosoc_jb

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

3. Download and install the Program and Debug software from:
   https://soc.microsemi.com/portal/default.aspx?r=3&p=f=ProgramDebug_v12_6_WIN

Note: On this web page, download the Program_Debug_v12.6_win.exe binary file. Installation of this executable file installs FlashPro Express and SmartDebug used for FPGA programming and debugging. 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.

2.3 Demo Resources

The mpf_dg0849_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, refer to Programming the Device, page 8.

2.4 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 150 MHz clock for the HDMI_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 oscillators, PF_XCVR_REF_CLK generates the following clocks:

• 148.5 MHz clock (LANE0_TX_CLK_R) for the 4K User Logic.

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

The following figure shows the clocking structure.

Figure 2 • Clocking Structure

2.5 Reset Structure

The Mi-V processor subsystem, XCVR, UART, 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 following figure shows the reset structure.

Table 2 • Jumper and Switch Settings

7. Power-up the HDMI monitor.
8. Power-up the board using the SW4 slide switch.

The PolarFire dual camera video and imaging hardware is set up. Refer to the following section to program the PolarFire device.

9. Connect the HDMI port of a HDMI output device such as laptop to the HDMI 2.0 RX port J35 connector on the video kit through an additional HDMI male to male cable. Make sure the HDMI output device uses a resolution of 1920 x1080p 60 Hz.
10. The video in the HDMI monitor is automatically switched to the video from HDMI input source.
11. Disconnect the HDMI RX cable to switch back to camera video.

2.7.2 Programming the Device

To program the PolarFire device with the job file provided as part of the design files using FlashPro Express software, refer to Appendix: Programming the Device Using FlashPro Express, page 12.

2.8 Running the Demo

The demo features receiving the MIPI Rx data from the two cameras with 4K resolution at 30 Frames Per Second (FPS). The frames from camera are stored in DDR and passed on to the display as per the display controller timing parameters. The image processing pipeline on the display side uses bayer interpolation, gamma correction, histogram, and image enhancement IPs to enhance the raw image from the camera. Also, the demo uses automatic camera exposure control based on the lighting conditions.

The demo also features HDMI Rx input at a resolution of 1920 x1080p 60 Hz. The HDMI input video is displayed on the HDMI monitor upon connecting a HDMI source at the RX port.

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

• Full HD output (1920×1080 60 Hz resolution)
• 4K output (3840×2160 30 Hz resolution)

The Full HD output supports PIP, panning, Edge Detection, and Image enhancements such as contrast, brightness, color balance, and alpha blending. The 4K output supports Image enhancements. The GUI control for image enhancements is common for both the video outputs.

Running the demo involves verifying the imaging and video settings using the Video_Control GUI and then observing the result on the HDMI monitor.

To use the demo GUI:

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

Figure 4 • Video_Contol GUI

2. Select the second largest COM port on the GUI and select the Connect option.

Figure 5 • Connecting the GUI and Video kit

3. The Connect button turns green indicating a successful connection.

Figure 6 • 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 7 • Adjusting Contrast and Brightness

5. Similarly, adjust the color balance of the image using the color balance sliders.
6. Adjust the Alpha slider. The alpha blending feature enables adjusting the transparency of the PIP image. When the alpha value is adjusted to minimum (0), the image disappears.

Note: Default image settings can be reverted by using the Reset option.

7. Switch to Edge Detection mode using the Edge option.
8. Select the PIP Menu to change the PIP settings.
9. Select the source of the PIP window between Camera 1 and Camera 2 using PIP: Source Select.
The position of the PIP window can be moved anywhere within the screen by dragging the pink Picture In Picture box. The Auto Mode Start option moves the PIP window automatically. The speed of this movement can be controlled using the Auto Mode Step slider.

Figure 8 • PIP Menu

10. Close the PIP Menu.
11. 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.
12. 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 9 • Panning Menu

13. Close the Panning Menu to return to the main GUI.
