[FFmpeg-devel] libavutil: optimize camellia cipher

[supraja reddy]

Hello,

I have attached a patch to optimize the camellia block cipher.
I ran crypto_bench on the optimized version. Here are the results of
runtime using crypto_bench.

Before the changes :
lavu       CAMELLIA     size: 1048576  runs:   1024  time:   32.541 +- 0.044

After the changes:
lavu       CAMELLIA     size: 1048576  runs:   1024  time:   24.589 +- 0.066

I ran this on a Linux x86_64 OS with Intel Core i5-3210M CPU.

Please let me know if there are any changes you would like.


Thanks,

Supraja
