More Information

Connect Tech’s FreeForm/Express S6 is a reconfigurable computing platform that is based on the Xilinx Spartan-6 FPGA featuring integrated PCI Express® blocks, advanced memory support, and 3.125 Gbps low-power transceivers. The FreeForm/Express S6 FPGA development board includes an industry-standard FPGA Mezzanine Card (FMC) connector, which provides a flexible I/O interface for future scaling and customization. The PCIe bus bandwidth ensures high speed communication between the host system and the application’s interfaces.

A wide range of available FMC modules adds interfaces such as ADC and digital video, which makes FreeForm/Express S6 a highly versatile platform for system development. Ideally suited for applications requiring both prototyping and field deployment including real-time data acquisition, high performance video processing, and software defined radio. FreeForm/Express S6 is optimized for embedded processor designs, supporting development with Xilinx’s MicroBlaze.
