Part 1: FPGA Development Board Introduction

Here, a brief introduction to the AX7021 ZYNQ FPGA development
platform.
The entire structure of the development board, the core board + carrier
board mode design. A high-speed inter-board connector is used between the
core board and the carrier board.
The core board is mainly composed of the minimum system of ZYNQ7020
+ 2 DDR3 + eMMC + QSPI FLASH. It undertakes the high-speed data
processing and storage function of the ZYNQ system. The data width between
the ZYNQ7020 and the two DDR3s is 32 bits, and the two DDR3 capacities up
to 1GB. The 32GB eMMC FLASH memory chip and 256Mb QSPI FLASH are
used to statically store the ZYNQ operating system, file system and user data.
Users can select different startup modes through the DIP switch on the core
board. The ZYNQ7020 uses Xilinx's Zynq7000 series of chips, model number
XC7Z020-2CLG484I. The ZYNQ7020 chip can be divided into processor
system part Processor
Programmable Logic (PL).
The carrier board expands the rich peripheral interface for the core board,
including 5 Gigabit Ethernet interfaces, 4-port USB2.0 HOST interfaces, 1-port
HDMI output interface, 1-port SD Card interface, 1-port UART USB serial port
interface, 1-port SD Card interface, 2-port 40-pin carrier headers and some
button LEDs.
