A web server is implemented based on the socket’s application program interface (API) provided by
the NicheStack TCP/IP Stack Nios II Edition running on a MicroC/OS-II RTOS to serve web
content from the DE4 development board. Using DHCP protocol, the web server is able to request a
valid IP from the Gateway. The server can process basic requests to serve HTML, JPEG, GIF, PNG,
JS, CSS, SWF, ICO files from a single zip file stored onto the flash memory on the DE4 board. In
addition, it also allows you to control various board elements from the web page which includes
controlling the LED lights, 7-segment display, and fan control.
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.
Before you begin to study this demo, we assume that you already have a basic knowledge of PHY
and MAC. In this case the PHY we use is Marvell 88E1111 (10/100/1000), and the MAC is Altera’s
Triple-speed Ethernet Soft-Core IP.
The following describes the SOPC system which contains a Nios II processor, On-Chip memory,
JTAG UART, timer, Triple-Speed Ethernet, Scatter-Gather DMA controller and peripherals which
are linked together in the Nios II hardware system to be used when building a project. In the
Triple-Speed Ethernet IP Core configuration, the interface is set to SGMII interface as well as using
