Acromag introduces two new mezzanine modules that provide a multi-channel 10GbE interface with an ASIC-based TCP offload engine (TOE) via SFP+ fibre/copper or XAUI ports for high-speed embedded computing applications.

Acromag’s new XMC-6260 and XMsC-6280 mezzanine modules provide a 10-gigabit Ethernet (10GbE) interface solution for data-intensive, real-time embedded computing systems. Ultra-high performance is achieved using a TCP/IP offload engine (TOE) ASIC connected to a PCI Express Gen2 x8 interface.

While the XMC-6260 has dual XAUI 10GBASE-KX4 ports and supports conduction-cooling or -40°C to 85°C operation, the XMC-6280 features four SFP+ ports for fibre or copper cables.

The new mezzanine modules find application in high-speed data storage, image collection/ transfer, distributed control networks, and board-to-board interfaces. All versions are available with lead or lead-free solder.

With the adoption of 10GbE for video and other data sources, even the most powerful processors require help managing the data flow to prevent performance bottlenecks. To solve this challenge, Acromag’s network interface modules pair a purpose-built, multi-protocol processor with up to four channels of 10GbE connectivity, offloading TCP overhead tasks from the host CPU to maintain maximum computing speeds.

To meet the needs of data-intensive real-time applications, these fully integrated network interface cards (NIC) employ the Chelsio T4 processor. This ASIC has four XGMAC (10GbE) interfaces and supports up to 1M connections. Five gigabits of DDR3 memory enhance the number of virtual connections. The T4 chip provides full offload support for TCP, UDP, iSCSI, and Fibre Channel over Ethernet (FCoE).

Functions also include high-performance packet switching, traffic filtering and management. By relieving the host CPU of these network processing tasks, one can achieve very low Ethernet latency and high-level determinism. Software drivers are available for Linux and Windows.

An 8-lane PCIe host interface provides a high-speed connection to the system processor. With support for 5Gbps data rates, the PCIe interface delivers up to 32Gbps of bandwidth to the server, enabling stateless offloads, packet filtering (firewall offload), and traffic shaping (media streaming).

Acromag’s XMC-6260 and XMC-6280 modules provide a complete and flexible TCP offload solution. The TOE ASIC has hundreds of programmable registers for protocol configuration and offload control. As a result, these modules can offload TCP processing per connection, per server, per interface. They can also globally and simultaneously tunnel traffic from non-offloaded connections to the host processor for the native TCP/IP stack to process.

Additionally, the modules provides a flexible zero-copy capability for regular TCP connections, requiring no changes to the sender, to deliver line rate performance with minimal CPU usage.

These network interface cards can also provide powerful packet switching and routing capabilities.
