Frank Barchard d981495b42 Hamming Distance using 16 bit accumulators ... Summing 16 bit hamming codes restricts the maximum length, but saves an inner loop instruction. The outer loop can sum the values. 32 bit Neon Now BenchmarkHammingDistance_Opt (78 ms) Was BenchmarkHammingDistance_Opt (92 ms) 64 bit Neon Now BenchmarkHammingDistance_Opt (85 ms) Was BenchmarkHammingDistance_Opt (92 ms) R=wangcheng@google.com TBR=kjellander@chromium.org BUG=libyuv:701 TEST=BenchmarkHammingDistance Change-Id: Ie40f0eac2f3339c33b833b42af5d394b122066ae Reviewed-on: https://chromium-review.googlesource.com/526932 Reviewed-by: Frank Barchard <fbarchard@google.com> Reviewed-by: Cheng Wang <wangcheng@google.com> Commit-Queue: Frank Barchard <fbarchard@google.com>		2017-06-07 23:23:24 +00:00
