## Summary Optimize crc32 standard(poly:0x04C11DB7) and crc32 castagnoli(poly:0x1EDC6F41) with arm crc32 extension instructions. For example, crc32 standard caculates(lookup crc32 table) 1812 bytes data, reduced the time from 118 us to 14 us through optimization. Performance improved ~700% ## Impact No. The new feature is disabled by default, open it when your arm chip has crc32 extension ## Testing build: fvp-armv8r-aarch32:nsh tested on a cortex-r52 cpu -- This is an automated message from the Apache Git Service.
