[PATCH] Optimize silk_LPC_inverse_pred_gain() for ARM NEON
Hi,
Attached is a patch with arm neon optimizations for
silk_LPC_inverse_pred_gain(). Please review.
Thanks,

[PATCH] Optimize silk_LPC_inverse_pred_gain() for ARM NEON
Hi Jean-Marc, (forgot cc opus@)
Thanks for creating the unit test code.
Attached is the updated optimization patch.

[PATCH] Optimize silk_LPC_inverse_pred_gain() for ARM NEON
...cit unit test. IIRC, the case could be triggered by the
following input vector:
A_QA[] = { 46596096, -72118272, 78532608, -69447680, 52707328,
-22073344, -19890176, 50507776, -54829056, 45518848, -33939456,
21086208, -7127040, -4136960, 3993600, -1699840 }
2) I'm not quite sure what to make of silk_LPC_inverse_pred_gain_Q24().
It seems to never be called anywhere -- except from the MIPS code. Maybe
it should just stay as it is (not renamed to _c()) but I need to check.
Any thoughts?
Cheers,
Jean-Marc

Several patches of ARM NEON optimization
I rebased my previous 3 patches to the current master with minor changes.
Patches 1 to 3 replace all my previous submitted patches.
Patches 4 and 5 are new.
Thanks,
Linfeng Zhang
