reverse ccitt

Could somebody please propose hardware for the Reverse CCITT CRC calculation
(not 0x1021 but 0x8408). 16 bit CRC with 8 bit data input.
Thanks a lot.
 

Hi,

If you have schematics for 0x1021 polynom you can easy modify circuit to 0x8408 polynom. You only need to change XOR feedback logic to 0x8408 polynom. You also need additional logic for 16bit CRC read or verification.
