Embedded System Project - IT4797 - SoICT - HUST

• Study to use PCIe IP Core, SG-DMA IP Core,... with Intel FPGA.
• Write an IP Core to implement convolution operator by kernel 3x3 and input image 640x480, fixed-point number, compatible with Avalon Video Streaming Interface.
• Display video via VGA, run demo with Gaussian, Sobel, Prewitt, Mean filter.

Getting Started

• PCIE_Display: Quartus project, I've used 17.1 version to build it, you can use both Lite/Standard Edition versions without any problem. Note: ip_repo sub-folder contains my convolution IP Core, verilog HDL code.
• PCIE_Driver: PCIe device driver to control SG-DMA, Frame Reader...

Prerequisites

• I use Ubuntu 14.04 for DE2i-150. Kernel version is 4.4.0. You can check your kernel version with this command:

$ uname -r

• Please add this two options into grub booting commands:

/etc/grub.conf: vmalloc=512MB intel_iommu=off

• With Ubuntu 14.04, you change this line in /etc/default/grub:

GRUB_CMDLINE_LINUX="vmalloc=512MB intel_iommu=off"

• Then update grub:

sudo update-grub

• If you're using another kernel version, maybe you need to modify device driver. To build device devicer:

$ cd driver
$ make

• To build application:

$ cd app
$ make

• You can run matlab file in Make Video folder to get input video, or you can download input video directly here:

https://drive.google.com/drive/folders/1-CMqv4Z6cPjSZiaYw8YN0BKHNSoodPCP

Installing

• Run quick_start.sh with sudo permission to install device driver and create device file automatically.

$ sudo ./quick_start.sh

• Or you can install device driver and create device file manually.

$ cd driver
$ sudo insmod altera_driver.ko
$ sudo mknod /dev/de2i150_altera c 91 1
$ sudo chmod 777 /dev/de2i150_altera

• Go to PCIE_Driver/app, run app.

$ cd app
$ sudo ./app

• Connect screen to FPGA VGA port, you'll see the results.

Running the tests

• Change states of SWs 0 to 6 to see results on screen. If all 7 SWs are 0, the original video is displayed. Else:

0000001: Gaussian filter, sigma equals 1.
0000010: Gaussian filter, sigma equals 2.
0000100: Sobel filter, x axis.
0001000: Sobel filter, y axis.
0010000: Prewitt filter, x axis.
0100000: Prewitt filter, y axis.
1000000: Mean filter.
