Subject: [PATCH] performance-neoncrc32-and-prfm-2
|
||||
|
||||
Analysis of gzip software by perf tool, found that crc32 and
|
||||
longest_match hotspots are very high.
|
||||
|
||||
On the ARM architecture, we can optimize the efficiency of
|
||||
crc32 through the interface provided by the neon instruction
|
||||
set, and optimize the performance of random access code through
|
||||
prefetch instructions.
|
||||
Modify by Li Qiang.
