This XILINX FPGA Video Processing development platform (module:
AV6045) adopts the core board + carrier board mode, which is convenient for
users to use the core board for secondary development.
This FPGA video image processing development platform is derived from
the improvement of our company's ALTERA video development board. In terms
of hardware design, we added HDMI input, DVI output, Gigabit Ethernet,
CMOS Camera interface and Micro in the original design. Peripherals such as
SD card slot. This greatly enriches the functions of the video image processing
board, not only satisfies the functions of FPGA video image processing, but
also provides network communication for video image storage and video
images. Therefore, this development platform can be called "professional" and
"all-round". Such a product is very suitable for students, engineers and other
groups engaged in FPGA video image processing or video image
communication and storage.

Part 1: FPGA Development Board Introduction
The entire structure of the AV6045 FPGA development board is inherited
from our consistent core board + carrier board mode. A high-speed inter-board
connector is used between the core board and the carrier board.
The core board is mainly composed of FPGA+ DDR3+ FLASH. It
undertakes the core algorithm of video image processing, fully utilizes the
parallel processing capability of FPGA, and the high-speed data reading and
writing between FPGA and DDR3. The bandwidth of the whole system is up to
10Gb/s (666M*). 16bit); In addition, DDR3 capacity is up to 2Gbit, which meets
the need for high buffers during video processing. The selected FPGA is the
high-speed FPGA chip of XC6SLX45-2FG484 of XILINX SPARTAN6 series.
The FPGA is packaged in BGA 484. SPARTAN6 FPGA integrated DDR
controller hard core, and DDR3 communication clock frequency reached
333Mhz, DDR3 internal 666Mhz, fully meet the needs of four 1080p video
processing.

board, and each interface chip and FPGA on the board are configured through
I2C.
Part 2: Function realization
Part 2.1: Video Input
The video development board can input 4 composite video signals through
TW2867, PAL/NTSC/SECAM automatically recognizes and output BT656; or
through SIL9013, can input HDMI video signals; or through CMOS interface,
can input image signals acquired by CMOS camera. Therefore, there are many

video sources available for development boards, such as:
1)Surveillance cameras
Through the FPGA development board, it is possible to realize
four-channel surveillance camera through the display (VGA/DVI/HDMI
interface, which can realize 1080p) for split-screen display. Our development
board is equivalent to the digital video host in the Figure below.
