This MPSoCs 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 Zynq UltraScale+ EV chip ZU4EV
solution, uses Processing System(PS)+Programmable Logic(PL) technology to
integrate dual-core ARM ARM Cortex-A53 and FPGA programmable logic on a
single chip. In addition, the PS side of the core board has 4 pieces of 1GB
high-speed DDR4 SDRAM chips, 1 piece of 8GB eMMC memory chip and 1
piece of 256Mb QSPI FLASH chip; the PL side of the core board has 1 piece of
1GB DDR4 SDRAM chip
In the design of carrier board, we have extended a wealth of interfaces for
users, such as 1 FMC LPC interface, 1 SATA M.2 interface, 1 DP interface, 1
PCIe x 2.0, 4 USB 3.0 Interface, 2 Gigabit Ethernet interfaces, 1 HDMI Output,
1 HDMI Input, 2 Uart, 1 SD card slot, 2-Channel CAN bus interfaces,
2-Channel RS485 bus interfaces, 1 MIPI Camera Interface. It meets users'
requirements for high-speed data exchange, data storage, Video transmission
processing, deep learning, artificial intelligence 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 MPSoCs development.

Part 1: FPGA Development Board Introduction
The entire structure of the AXU4EV 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 ACU4EV +
5 DDR4 + eMMC + QSPI FLASH, ACU4EV uses Xilinx's Zynq UltraScale+
MPSoCs EV chip, the model number is XCZU4EV-1SFVC784I. ZU4EV chip
can be divided into processor system part Processor System (PS) and
programmable logic part Programmable Logic (PL). On the PS side and PL
side of the ZU4EV chip, there are 4 DDR4 and 1 DDR4 respectively, each with
a capacity of up to 1GB, which enables the ARM system and FPGA system to
independently process and store data. The 8GB eMMC FLASH memory chip
and a 256Mb QSPI FLASH which are on the PS side, used to statically store
the operating system, file system and user data of MPSoCs.
The AXU4EV-P carrier board expands its rich peripheral interface,
including 1 M.2 interface, 1 DP output interface, 4 USB 3.0 Interface, 2 Gigabit
Ethernet interfaces, 1 PCIE x 2.0 Interface, 2 SFP, 2 Uart, 1 SD card slot, 1
HDMI Output Interface, 1 HDMI Input Interface, 1 FMC Interface, 2-Channel
CAN bus interfaces, 2-Channel RS485 bus interfaces, 1 MIPI Camera Interface
and some keys and LEDs.
The following figure shows the structure of the entire development system:
