ESC – Express Logic’s NetX achieves near wire speed on Freescale Kinetis processor

Express Logic, Inc.'s NetX TCP/IP stack has achieved 94 Mbps, or 94% wire speed, on Freescale’s ARM Cortex-M4-based Kinetis processor, which has a 100-Mbps Ethernet port that enables transfers at up to wire speed. NetX performed at 94 Mbps while using less than 50% of the processor’s cycles. This frugal use of CPU cycles allows many other product functions to run during TCP/IP activity without slowing network performance.

NetX performance was measured using the open-source, industry-standard, network throughput benchmark tool “iperf.”  Iperf was run on a Windows host, connected to a Freescale Kinetis target board via Ethernet. The iperf TCP and UDP results were served by NetX as a Web page, displayed by Internet Explorer on the host.

Shipping and Availability
NetX TCP/IP is available for ThreadX in full source code form, royalty free, with project licenses starting at $12,500.
