2.6.6.5. Save Power by Disabling CRC Blocks When Not in Use

CRC designs are heavy consumers of dynamic power because the logic toggles whenever there is a change in the design.

To save power, use clock enables to disable the CRC function for every clock cycle that the logic is not required. Some designs don’t check the CRC results for a few clock cycles while other logic is performing. It is valuable to disable the CRC function even for this short amount of time.
