// Note:
|
|
// 1. src is not always 32-bit aligned, so don't call vld1_lane_u32(src).
|
|
// 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%.
