Vendor Unique Intel CRC32C

■

Vendor Unique Intel CRC32C

The following is a sample ‘C program’ to software generate the Intel CRC32C 
on an i386 class processor. This example also includes the assembly 
language code to utilize the Nehalem class server with SSE4_2 support to 
generate this CRC with the hardware CRC32 instructions.
