1Gb Ethernet module

The hardware based Gigabit data module is designed for applications that require very high speed data throughput over Ethernet. The difference with a software based solution is the sustained data rate that can be reached. A software solution will typically go up to some 10 to 150 Mbits/sec (depending on the processor speed).

This hardware based solution is capable of sending data, almost at the full bandwidth available: 900Mbits/sec.

Typical applications are:

• Broadcast video over Ethernet.
• Highspeed data-acquisition devices.
• Realtime data conversion bridges.
• Network switches.

Description

Data is read into a (hardware controlled) buffer. That buffer is sent directly to the low-level part of the TCP/IP stack. The TCP/IP stack runs in the software section (embedded processor) to support the required protocols like DHCP and ARP.

The high performance is possible because the software part does not have to handle anything of the data stream.
