This design example shows a HTTP server using the sockets interface of the NicheStack™ TCP/IP

Stack Nios II Edition on MicroC/OS-II to serve web content from the DE2-115 board. The server

can process basic requests to serve HTML, JPEG, GIF, PNG, JS, CSS, SWF, ICO files from the

Altera read-only .zip file system. Additionally, it allows users to control various board components

from the web page.

As Part of the Nios II EDS, NicheStack™ TCP/IP Network Stack is a complete networking

software suite designed to provide an optimal solution for network related applications accompany

Nios II.

Using this demo, we assume that you already have a basic knowledge of TCP/IP protocols.

The following describes the related SOPC system. The SOPC system used in this demo contains

Nios II processor, On-Chip memory, JTAG UART, timer, Triple-Speed Ethernet, Scatter-Gather

DMA controller and other peripherals etc. In the configuration page of the Altera Triple-Speed
