This design example consists of both hardware and software. The hardware section consists of the Nios® II/f core with the reset vector pointing to the flash memory and exception vector pointing to the DDR3 memory. The hardware system also consists of the Triple Speed Ethernet MAC and a scatter-gather direct memory access core (PDF) for both TX and RX.
You can use the Triple Speed Ethernet design to evaluate the Triple Speed Ethernet media access control (MAC) or use it as a starting point for your own Ethernet system design. This design supports the following Altera® development kits:
- Stratix® IV GX FPGA Development Kit (EP4SGX230)
- Altera Embedded Systems Development Kit, Cyclone® III Edition (EP3C120)
