FFT FPGA Benchmark Results

The benchmark results are given divided by the used version of the benchmark, since internal changes in the benchmark code might lead to different performance results. All measurements were done with a data array of 2GB size. The measurements were executed 10 times and the best result is published.

The results and the used configuration is given in Table 6 and are also available as CSV.
