=== Whetstone Benchmark === M2 (array)... OK M3 (proc array)... OK M4 (conditionals)... OK M6 (log/exp/sqrt)... OK M7 (proc calls)... OK M8 (trig)... OK Passes: 10 Elapsed: 2191 ms KWIPS: 4564 Whetstone complete. The first Benchmarks run on an xilinx axu3eg - using musashi on arm and the FPU running on the PL fabric.
