|
|
From Intel Westmere and AMD Bulldozer processor with SSE4.2 and PCLMULQDQ supported, the processor will support CRC32 PCLMULQDQ
|
|
implementation using hardware accelerated PCLMULQDQ instruction. This option will create 'crc32-pclmul' module, which will enable
|
|
any routine to use the CRC-32-IEEE 802.3 checksum and gain better performance as compared with the table implementation
