somehow strange, becouse tested examples showed better performance for arm than dsp core:

/examples/c6runapp/emqbit# ./benc h_arm N=16, nTimes=100: Dot with C code => time:3.1e-05 s N=16, nTimes=100: Distance with C code => time:9.1e-05 s N=32, nTimes=100: Dot with C code => time:6.2e-05 s N=32, nTimes=100: Distance with C code => time:0.000152 s N=64, nTimes=100: Dot with C code => time:0.000153 s N=64, nTimes=100: Distance with C code => time:0.000305 s N=128, nTimes=100: Dot with C code => time:0.000305 s N=128, nTimes=100: Distance with C code => time:0.00058 s N=256, nTimes=100: Dot with C code => time:0.000579 s N=256, nTimes=100: Distance with C code => time:0.00116 s N=512, nTimes=100: Dot with C code => time:0.00116 s N=512, nTimes=100: Distance with C code => time:0.003113 s N=1024, nTimes=100: Dot with C code => time:0.002289 s N=1024, nTimes=100: Distance with C code => time:0.005066 s N=2048, nTimes=100: Dot with C code => time:0.005066 s N=2048, nTimes=100: Distance with C code => time:0.009491 s N=4096, nTimes=100: Dot with C code => time:0.009613 s N=4096, nTimes=100: Distance with C code => time:0.018616 s N=8192, nTimes=100: Dot with C code => time:0.01825 s N=8192, nTimes=100: Distance with C code => time:0.036865 s N=16384, nTimes=100: Dot with C code => time:0.036468 s N=16384, nTimes=100: Distance with C code => time:0.073364 s
