Server issuing commands over a TCP/IP socket to the Ethernet-connected NicheStack TCP/IP Stack
running on the DE4 board with a Simple Socket Server. The Simple Socket Server continues to
listen for commands on a TCP/IP port and operates the DE4 LEDs according to the commands from
the telnet client. NicheStack TCP/IP stack uses the MicroC/OS-II RTOS multithreaded environment
to provide immediate access to a stack for Ethernet connectivity for the Nios II processor. The Nios
II processor system contains an Ethernet interface, or media access control (MAC)
How the Ethernet demonstration is built
In this following section we describe how to build the demonstration through the SOPC builder. The
SOPC system includes the CPU processor, On-Chip memory, JTAG UART, system ID, timer,
Triple-Speed Ethernet, Scatter-Gather DMA Controllers and peripherals which are linked together
contained in the Nios II hardware system that are used when building a project.
Figure 5–12
presents the overall setup of the SOPC builder from the Ethernet Simple Socket Server project.

In the Triple-Speed Ethernet IP Core configuration, the interface is set to SGMII as well as using
the internal FIFO shown in
