DSX50WZ: Spartan-3AN FPGA development board with Ethernet
Xilinx XC3S50AN + WIZnet W5300 = small, fast, low power web server for only $119
Digital Shortcut Inc. DSX50WZ board combines Xilinx's XC3S50AN Spartan-3AN FPGA and WIZnet W5300 Hardwired Network Protocol Ethernet Controller.
When your project calls for Ethernet interface it gives you a head start in your embedded project design process.
This small factor board may be configured as a very efficient web server and still has most of the XC3S50 FPGA resources
available for your application. Just imagine the possibilities of having an Internet Appliance with power consumption less
then 1Watt and capable of effectively serving rich web pages with performance on par with "big" servers. Not to mention
at the same time having ~33k gates available for your application. The W5300 Ethernet Controller makes complex task of TCP/IP packet
processing and serving web pages no more difficult than working with UART. If you are starting a new project with FPGA connected
to Ethernet, want to learn FPGA and PicoBlaze programming or just need a web server/network connection for your "older design"
it is the perfect board for you.

8.0 MByte/s measured when uploading 1 GB file using HTTP POST metod in 125 seconds.
4.8 MByte/s measured when serving 1 GB file using HTTP GET metod in 208 seconds.

Unique for this board is that W5300, EEPROM, RS232 and SD card are connected to Bank 3 of FPGA leaving Bank 0, Bank 1 and Bank 2 available for user application.
There are 53 pins routed to headers, most of them are routed as a differential pairs.
This board is shipped preprogrammed with our demo web server software/hardware. Server runs on PicoBlaze
microprocessor and is capable of serving selected pages of our web site including this one. Web pages in
compressed format are stored in internal flash of Spartan3AN. One of the demo pages
shows how to access FPGA logic using
"XMLHttpRequest" function and java script. Demo comes as a complete working Xilinx ISE WebPACK 10.1 project
with all sources and takes less than 33% of FPGA resources
. We also included our "SiteBuilder" Tcl/Tk application
for converting web pages into a format loadable into FPGA internal flash. Please go to our
page and grab "Software Package" for your board version.
ISE® WebPACK™ software is the ideal downloadable solution for FPGA and CPLD design offering HDL synthesis
and simulation, implementation, device fitting, and JTAG programming all of it free. Xilinx has created a solution that allows
convenient productivity by providing a design solution that is always up to date with error-free downloading
and single file installation. You only need to buy a programming cable. For development we recommend "Platform Cable USB II".
