[opus] [RFC PATCH v1 2/4] armv7(float): Optimize decode usecase using NE10 library

Viswanath Puttagunta viswanath.puttagunta at linaro.org
Wed Mar 18 12:49:30 PDT 2015


Optimize opus decode (float only) use case using ARM NE10.
Mainly effects opus_ifft and ctl_mdct_backward and related
functions.

Work based on previous Encode optimization using ARM NE10
library.

TBD: Add commit id of upstream Encode NE10 optimization patch
so that users have reference of how to enable this optimization
