New high-performance Gigabit Ethernet FPGA module

Orange Tree Technologies has announced a compact new addition to its product family, the ZestET2-NJ, a high-performance Gigabit Ethernet FPGA module. Comprising Gigabit Ethernet processing engine, Xilinx Artix-7 FPGA, DDR3 memory and general purpose I/O, it is aimed at data acquisition and control applications in markets such as industrial vision, radar, sonar and medical imaging. The small size of the new addition makes it ideal for integration into customers' end products and as you would expect from Orange Tree boards, it concentrates on high performance without the need for any unnecessary peripherals. Delivering the maximum sustained Ethernet bandwidth of over 100MBytes/sec in both directions simultaneously, it is ideal for high-bandwidth data-acquisition and control applications. The User FPGA is the Xilinx Artix-7 XC7A35T with over 33,000 logic cells, 1.8Mbits of Block RAM and 90 DSP slices. It is tightly coupled with 512MBytes of 400MHz DDR3 SDRAM, giving it an ample memory bandwidth of 1.6GBytes/sec for high speed processing and formatting of streaming data. With ease of integration in mind, there are 105 FPGA IO pins available for connection to the user's equipment, says the company. Charles Sweeney, hardware director, said: "With the increasing use of Ethernet in many different markets such as industrial control, machine vision, defence and the medical sector, ZestET2-NJ can speed the time to market for many companies, creating a key advantage for them." Ease of use has been a major design consideration for the product team, with Orange Tree's proprietary GigEx chip handling all the Ethernet protocols, saving application designers and companies the headache of having to get to grips with the complexity of TCP/IP or creating their own Ethernet interface. Now in its third generation, GigEx adds an internal user programmable SPARC-compatible CPU, which can be used for example to implement higher level Ethernet protocols such as GigE Vision. SPARC programming tools are supplied free with the module. Alternatively this CPU can be left unprogrammed and GigEx will then handle the standard Ethernet protocols. Matt Bowen, software director, added: "We based the design of GigEx on the TCP/IP engine of our highly successful previous Ethernet products. The new product design has therefore been shaped by over 5 years’ practical user experience". With the proprietary protocol chip GigEx handling the whole TCP/IP stack at over 100MBytes/sec in each direction simultaneously, it allows the User FPGA to be dedicated entirely to the application for maximum efficiency. The module measures just 40mm x 50mm, making it ideal for integration into end products. The TCP/IP engine in GigEx runs at 10/100/1000 Mbits/sec and implements the following protocols: TCP/IP, UDP, ARP, IPv4, ICMP, IGMP, PTP and HTTP. For real-time applications, Precision Time Protocol (PTP) and SyncE offer time of day and a 125MHz clock synchronised across the network to other network devices.
