Figure 6-32 PHY connected to the MAC via RGMII
After the SOPC hardware project has been built, develop the SOPC software project, whose basic
architecture is shown in Figure 6-33. The top block contains the Nios II processor and the
necessary hardware to be implemented into the DE2-115 host board. The software device drivers
contain the necessary device drivers needed for the Ethernet and other hardware components to
work. The HAL API block provides the interface for the software device drivers, while the Micro
C/OS-II provides communication services to the NicheStack™ and Web Server. The NicheStack™
TCP/IP Stack software block provides networking services to the application block where it
contains the tasks for Web Server.
