Professional  ALTERA  FPGA  Video  Processing  development  platform 

(module:  AV4075)  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 AX822. 
In terms of hardware design, we added HDMI input, Gigabit Ethernet, CMOS 
Camera  interface  and  Micro  in  the  original  design.  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.
