| FreeForm/104 is a PC/104 based card that
features a reconfigurable FPGA for digital
I/O and control applications.
Based on Xilinx’s Spartan 3E, Connect Tech’s
FreeForm/104 offers off-the-shelf flexibility.
The FPGA is stored on-board in flash
memory, allowing users to accomodate
design changes at run time making it ideal
for high speed, compute-intensive,
reconfigurable applications.
Customized FPGA configurations can be
developed easily by the user with Xilinx’s
free ISE Webpack software at,
http://www.xilinx.com/ise/logic_design_prod/webpack.htm or through Connect Tech’s
engineering services.
The versatility, high speed processing core
and less than 25 ns transfer function of
FreeForm/104 makes it ideal for applications
including; DSP, software defined radio,
aerospace, defense systems, computer
hardware emulation, production or laboratory
testing and industrial process monitoring and control.
