IntelFPGA Cyclone V SoC OpenCL

Hardware Architecture

Supported Boards

• DE1-SoC
• DE10-Nano
• DE10-Standard
• DE10-Nano+Mi-LCD

Supported USB Cameras

• UVC (USB video device class) USB Cameras,for example Logitech C270

SD Card Image Features

• now,FPGA reconfigurable
• IntelFPGA OpenCL SDK 17.1 , 18.1 ,19.1
• ubuntu 18.04 root file system
• LXDE desktop
• support x2go server (run desktop through ethernet)
• also working with terasic's OpenCL hardware template BSP(x2go only with no vedio ip core,here)
• All in one ( DE1-SoC , DE10-Nano and DE10-Standard)
• usb host and uvc driver for UVC USB cameras

You can downlaod the c5soc_opencl_lxde_fpga_reconfigurable_20201027.img all in one SD card Image file here Baidu Cloud Link or Google Drive Link.

Run default OpenCL Application

1. Download the Image file and write it into the microSD card
2. run update_rbf_and_dtb.bat or sh ./update_rbf_and_dtb.sh on PC to update rbf and dtb for target board
3. Insert the microSD card to the DE10-nano , DE1-SoC or DE10-Standard board
4. Set the MSEL[4:0] on your board to 01010 , SW10(1 to 6) on,off,on,off,on,N/A
5. Connect a monitor to the HDMI or VGA port on baord
6. Conect USB mouse and keyboard to the USB ports on the board
7. Conect UART to PC
8. Power on the board and you will see the LXDE graphical environment
9. Open the LXterminal on the desktop
10. source the init_opencl_17.1.sh file
11. run sobel host host.17.1.run directly. (which keep same as your target board and the OpenCL SDK version )

OpenCL Hardware Template

Target Board	Hardware Template wtih VIP core	terasic's Hardware Template
DE1SOC	de1soc_sharedonly_vga	de1soc_sharedonly
DE10-nano	de10_nano_sharedonly_hdmi	de10_nano_sharedonly
DE10-Standard	de10_standard_sharedonly_vga	de10_standard_sharedonly

de10_nano_sharedonly_mil for DE10-nano + Mi_LCD

Demos

colorApp

A UVC usb camera application program is used to convert YUYV to RGB and Gray by using opencl.

Host usage:

colorApp.run -w960 -h720 
colorApp.run -w640 -h480 -r2 -g1 -b2 -u700 -d200 

camera_sobel

YUYV --> Y(gray) --> sobel

camera_sobel.run -v  //"-v" hardware mode

sobel_filter

do sobel by using four methods : arm , neon , opencl ,opencl with shared memory

Methods	Frequency	Time
Cortex-A9	800Mhz	168ms
Neon	?	37ms
OpenCL Memory Copy	140Mhz	256ms
OpenCL Shared Memory	140Mhz	14.8ms

Host useage:

number 1 2 3 4 5 6 different ways to run filter
"+"  Increase filter threshold
"="  Reset filter threshold to default
 " q/<enter>/<esc>" Quit the program

Mandelbrot

Host useage:

mandelbrot -w=800 -h=640 -c=32

History
