The GateFlow product line includes GateFlow Installed Cores and GateFlow FPGA Design Kit. Model 6235 includes two complete acquisition and receiver channels in a VIM-2 module. The GateFlow FFT executes a pipelined complex 4k-point radix-4 FFE in 10.24 usec. With two 100 MHz A/Ds on the Model 6235, the GateFlow FFT can handle both A/Ds with 50% input overlap processing and zero data loss. The execution speed for the 1k-point complex FFT is 2.56 usec.
