Variable arm_nn_tanh_lut_f32

Variable Documentation

const float32_t arm_nn_tanh_lut_f32[385]

LUT for tanh(x) sampled over x in [0, 6] for float32 helpers.

Stores 385 samples so interpolation can safely read lut[idx + 1] while indexing the 384 fractional segments across the interval. The grid spacing (6/384 == 1/64) matches the earlier 257-entry [0, 4] table, so entries 0..256 are bit-identical to it and the index multiplier is unchanged. Generated by scripts/gen_tanh_lut_f32.py.
