* Kounavis and Frank L. Berry from Intel Corp.
|
|
* http://www.intel.com/technology/comms/perfnet/download/CRC_generators.pdf
|
|
*
|
|
* This code was made to be slightly less confusing with macros, which
|
|
* I suppose is somewhat ironic.
|
|
*
|
|
* The code had to be changed for non reflected on the output register
|
|
* since that's the method Quake uses.
|
|
*
|
|
* The code also had to be changed for CRC16, which is slightly harder
|
|
* since the CRC32 method in the original Intel paper used a different
|
|
* bit order convention.
|
|
*
|
|
* Notes about the table:
|
|
* - It's exactly 4K in size
|
|
* - 64 elements fit in a cache line
|
|
* - can do 8 iterations unrolled 8 times for free
|
|
* - The first 256 elements of the table are standard CRC16 table
|
|
*
|
|
* Table can be generated with the following utility:
