Cheap Ethernet interface |
|
Realization of Ethernet interface and protocols optimized for minimal external components and FPGA resources. |
FPGA may connecting through transformer or directly to twisted pairs (on your own risk). |
|
Features |
- 10BASE-TX interface (10 MBit/sec) full-duplex (thanks to fpga4fun.com). |
- Base functional of ARP (reqest, reply), ICMP (reply), UDP protocols (server, client). |
- Maximum packet size is 1 kb (fragmentation not supported). |
|
Required 50MHz/48Mhz and 20MHz clocks, 8kbit block memory, ~800 slices. |
Tested on Spartan 3E 500 with transformer and direct connection to twisted pair. |
