DSPCARD was designed for high speed digital signal processing and software defined radio. Schematics are available for download under the GPL in both PDF and gSchem format. It contains an Analog devices Blackfin DSP operating at 390MHz and a Xilinx Spartan III XC3S400 or XC3S1000 FPGA (FT256 BGA package). The DSP and FPGA both have 32MB of SDRAM. A pair of 80 pin 0.5mm pitch headers provide access to DSP and FPGA signals.
