| | | | | | | | | | | | | | | | | | | | | | | | | 58893 decicycles in deemphasis_c, 130548 runs, 524 skips 9475 decicycles in deemphasis_fma3, 130686 runs, 386 skips -> 6.21x speedup 24866 decicycles in postfilter_c, 65386 runs, 150 skips 5268 decicycles in postfilter_fma3, 65505 runs, 31 skips -> 4.72x speedup Total decoder speedup: ~14% Deemphasis SIMD based on the following unrolling: const float c1 = CELT_EMPH_COEFF, c2 = c1*c1, c3 = c2*c1, c4 = c3*c1; float state = coeff; for (int i = 0; i < len; i += 4) { y[0] = x[0] + c1*state; y[1] = x[1] + c2*state + c1*x[0]; y[2] = x[2] + c3*state + c1*x[1] + c2*x[0]; y[3] = x[3] + c4*state + c1*x[2] + c2*x[1] + c3*x[0]; state = y[3]; y += 4; x += 4; }

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modeled from the prores version. Clips to [0;1023] and is bitexact. Bitexactness requires to add offsets in different places compared to prores or C, and makes the function approximately 2% slower. For 16 frames of a DNxHD 4:2:2 10bits test sequence: C: 60861 decicycles in idct, 1048205 runs, 371 skips sse2: 27567 decicycles in idct, 1048216 runs, 360 skips avx: 26272 decicycles in idct, 1048171 runs, 405 skips The add version is not implemented, so the corresponding dsp function is set to NULL to make it clear in a code executing it.
