| // 2. After refactoring the shared code in kernel loops with inline functions, |
| // the decoder speed dropped a lot when using gcc compiler. Therefore there is |
| // no refactoring for those parts by now. |
| // 3. For horizontal convolve, there is an alternative optimization that |
| // convolves a single row in each loop. For each row, 8 sample banks with 4 or 8 |
| // samples in each are read from memory: src, (src+1), (src+2), (src+3), |
| // (src+4), (src+5), (src+6), (src+7), or prepared by vector extract |
| // instructions. This optimization is much faster in speed unit test, but slowed |
| // down the whole decoder by 5%. |
