Part 2: ZYQN Chip

The development board uses Xilinx's Zynq7000 series chip, model
XC7Z020-2CLG484I. The chip's PS system integrates two ARM CortexTM-A9
processors, AMBA® interconnects, internal memory, external memory
interfaces and peripherals. These peripherals mainly include USB bus interface,
Ethernet interface, SD/SDIO interface, I2C bus interface, CAN bus interface,
UART interface, GPIO, etc. The PS can operate independently and start up at
power up or reset. Figure 2-1 detailed the Overall Block Diagram of the
ZYNQ7000 Chip.
