Figure 1-1: The Schematic Diagram of the AX7450
Through this diagram, you can see the interfaces and functions that the
AX7450 FPGA Development Board contains:
 Xilinx ARM+FPGA chip Zynq-7000 XC7Z100-2FFG900
 DDR3
With 6 large-capacity 512M bytes (3GB total), high-speed DDR3
SDRAM. Two of them are mounted on the PS side to form a 32-bit data
width, which can be used as a cache for ZYNQ chip data, or as a
memory for operating system operation; the other 4 are mounted on the
PL side to form a 64-bit data width and can be used as an FPGA Data
storage, image analysis cache, data processing.
 eMMC
The PS side mounts an 8GB eMMC FLASH memory chip to store user
