Express Logic's NetX Duo TCP/IP Stack Attains Near-Wire Speed on Xilinx's Zynq-7000 Platform
December 11, 2012
In an effort to facilitate performance-conscious developers working on Xilinx’s Zynq-7000 device applications for lower development costs and faster time-to-market, Express Logic, Inc. – a company specializing in royalty-free, real-time operating systems (RTOS) – announced that its NetXDuo TCP/IP stack has achieved near-wire speed of 910-940 Mbps on Zynq-7000.
Xilinx’s Zynq-7000 are All Programmable system on chip (SoC) devices that combine an ARM dual-core Cortex-A9 MPCore processing system with advanced 28nm programmable logic.
Express Logic officials said that NetX Duo’s functionality and efficiency would enable Zynq-7000 devices to deliver a combination of maximum performance and robust connectivity, reducing design costs and speeding time-to-market.
Providing both IPv4 and IPv6 capabilities in a dual-stack product, Express Logic’s NetX Duo TCP/IP stack is available in full source code form, royalty free, with project licenses starting at $18,750.
Featuring Piconet architecture, the NetX Duo is fully integrated with ThreadX. In addition, it can implement all IPv4 features available in NetX 5.x; IPv6 header and extension header processing; neighbor discovery protocol; router discovery protocol; Stateless Address Auto configuration; and more.
The NetX Duo dual IPv4/IPv 6 TCP/IP stack currently supports more than 12 application protocols, including TCP/IP, UDP, DHCP, FTP, SNMP, and others that make it ideal for the high-performance connectivity needs of modern devices used in consumer, medical and industrial spaces.
NetX Duo’s performance was measured using iperf – the open-source benchmark tool used for measuring network throughput. iperf runs on a Windows host connected to a Xilinx Zynq-7000 SoC ZC702 Evaluation Kit via Ethernet.
According to a recent statement, the iperf TCP and UDP results were served by NetX Duo as a webpage and displayed by Internet Explorer on the host PC.
In order to attain the near-wire speeds, NetX Duo takes advantage of Zynq-7000’s gigabit Ethernet port, hardware checksum accelerator, and dedicated Ethernet MAC DMA engine integrated with its programmable logic.
This arrangement helps in maximizing network transfer speed.
Unlike other TCP/IP stacks, NetX Duo is capable of attaining 91-94 percent of maximum wire speed on Zynq-7000 devices running on only one of its 2 Cortex-A9 processors, freeing up the other A9 processor for functions that can run simultaneously without slowing network performance.
“The Ethernet throughput achieved by Express Logic’s NextX Duo stack on the Zynq-7000 All Programmable SoC is outstanding. The Zynq-7000 architecture was designed to enable the highest Ethernet throughput, and the NetX Duo performance results validate many of our architectural choices,” said Greg Brown, director of processing technical marketing, Xilinx. “Ethernet is ubiquitous, and the NetX Duo stack offers a very appealing solution for many of the applications that the Zynq-7000 devices serve.”
In recent news, Xilinx was assigned patents for an integrated circuit, providing improved feedback of a signal and for the nonvolatile recording of Integrated Circuit-r data.
