The interfaces and features included in the development board.
 ZYNQ7000 Core Board
It consists of XC7Z020+1GB DDR3+32GB eMMC FLASH + 256Mb QSPI
FLASH. In addition, two crystal oscillators provide clocks, one is 33.3333MHz
for PS system and the other is 50MHz for PL logic.
 Gigabit Ethernet Interface
5 channels 10/100M/1000M Ethernet RJ45 interface for Ethernet data
exchange with computers or other network devices. The network interface chip
uses Micrel's KSZ9031 industrial grade GPHY chip, one Ethernet connection to
the PS end of the ZYNQ chip, and four Ethernet connections to the PL end of the
ZYNQ chip.
