As Part of the Nios II, NicheStack TCP/IP Network Stack is a software suite of networking
protocols designed to provide an optimal solution for designing network-connected embedded
devices with the Nios II processor. A telnet client application is used to communicate with the
simple socket server issuing commands over a TCP/IP socket to the Ethernet-connected NicheStack
TCP/IP Stack running Nios II on the DE3 host board with a simple socket server. The Simple
Socket Server continues to listen for commands on a TCP/IP port and operates the DE3 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).

The section describes the steps using Quartus II, Nios II, and SOPC builder in generating the
demonstration.
The demonstration is setup using the DE3 System builder (v1.4.2) by configuring the DE3 I/O
components and also building a connection between DE3 and HSMC-NET. In DE3 configuration
we enabled the IO HSTC connector Group C to connect to the HSMC-NET shown in
Figure 4-2 .
Also, we want to enable the IO Group B connector to use the DDR2 SO-DIMM, in addition
enabling LED, Seg7 and Button which are used in the demonstration.
