Supported USB Cameras

UVC (USB video device class) USB Cameras,for example Logitech C270
USB Cameras supported by gspca driver
etc.

SD Card Image Features

now,FPGA reconfigurable (c5soc_opencl_lxde_fpga_reconfigurable.img only)
both IntelFPGA OpenCL SDK 16.1 and 17.1
ubuntu 16.04 and 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,see here)
also working without OpenCL
All in one ( DE1-SoC , DE10-Nano and DE10-Standard)
usb host and uvc driver for UVC cameras

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

Run OpenCL Application

Download the Image file and write it into the microSD card
Cpoy the BOARD_NAME_APP.rbf and BOARD_NAME_socfpga.dtb ( keep the BOARD_NAME same as your target board) to Windows fat32 partition and rename them to opencl.rbf and socfpga.dtb
Insert the programmed microSD card to the DE10-nano or DE1-SoC or DE10-Standard board
Set the MSEL[4:0] on your board to 01010 , SW10(1 to 6) on,off,on,off,on,N/A
Connect a monitor to the HDMI or VGA port on baord
Conect USB mouse and keyboard to the USB ports on the board
Conect UART to PC (must conect to PC or Power)
Power on the board and you will see the LXDE graphical environment
Open the console (Ctrl+Alt+T) on the desktop
source the init_opencl_16.1.sh or init_opencl_17.1.sh file
run OpenCL host (which keep same as your target board and the OpenCL SDK version ) directly.

OpenCL Hardware Template

Both supports IntelFPGA SDK for OpenCL 16.1 and 17.1

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

App

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 -h  //"-h" 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
