This ZYNQ7000 FPGA development platform adopts the core board +
carrier board mode, which is convenient for users to use the core board for
secondary development. The core board uses XILINX's Zynq7000 SOC chip
XC7Z010 solution, uses ARM+FPGA SOC technology to integrate dual-core
ARM Cortex-A9 and FPGA programmable logic on a single chip. In addition,
the core board contains 2 pieces of 512MB high-speed DDR3 SDRAM chips,
and 1 piece of 256Mb QSPI FLASH chip.
In the design of carrier board, we have extended a wealth of interfaces for
users, such as 1 Gigabit Ethernet interfaces, 1 USB2.0 HOST interface, 1
HDMI output interface, 1 UART USB interface. 1 SD card slot, 2-Channel CAN
bus interfaces, 2-Channel RS485 bus interfaces, 2-Channel AD input interface,
2-Channel 40-pin expansion header, some keys and LEDs. It meets users'
requirements for high-speed Ethernet data exchange, data storage, video
transmission processing and industrial control. It is a "professional" ZYNQ
development platform. For high-speed data transmission and exchange,
pre-verification and post-application of data processing is possible. This
product is very suitable for students, engineers and other groups engaged in
ZYNQ development.

Part 1: FPGA Development Board Introduction
The entire structure of the AX7Z010 FPGA development board is inherited
from our consistent core board + carrier board model. A high-speed inter-board
connector is used between the core board and the carrier board.
The core board is mainly composed of the smallest system of XC7Z010 +
2 DDR3 + QSPI FLASH, which is responsible for the high-speed data
processing and storage functions of the ZYNQ system. The data width between
the ZYNQ 7010 and the two DDR3 chips is 32 bits. The capacity of two DDR3
chips is up to 512MB. ZYNQ7010 uses Xilinx's Zynq7000 series chip, the
model number is XC7Z010-1CLG400I. ZYNQ7010 chip can be divided into
processor system part Processor System (PS) and programmable logic part
Programmable Logic (PL)
The AX7Z010 carrier board expands its rich peripheral interface, including
1 Gigabit Ethernet interfaces, 1 USB2.0 HOST interface, 1 HDMI output
interface, 1 UART USB interface. 1 SD card slot, 2-Channel CAN bus
interfaces, 2-Channel RS485 bus interfaces, 2-Channel AD input interface,
2-Channel 40-pin expansion header, some keys and LEDs.
The following figure shows the structure of the entire development system:
