optimization - How to increase the performance of the library on TI Sitara am335x? -


i using openssl library version 1.0.2 encryption , decryption of files in project. encryption , decryption functions take time , whole application performance gets worse.

i using ti sitara am335x processor , has cryptographic accelerator in it. not giving performance because of system/application constraint. tried optimize openssl library neon coprocessor (auto vectorization) using following flags

-o3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -mfloat-abi=hard

even 1 failing give performance.

apart optimizing application, how can deal library side?
