CRC-16 calculation with Cyclic Redundancy Check (CRC) Controller Module

Hello Roland,

No, our CRC is based on a 64-bit PSA derived from a primitive polynomial as per the following equation (Fixed Polynomial, hence cannot be changed)

f(x) = x64+ x4+ x3+ x + 1.

During a non-doubleword write access to PSA, all unwritten byte lanes are padded with zero’s before compression, and the compressed value is always expressed in 64 bit.

CRC module available in Hercules platform is mainly targeted for verifying the integrity of our memory sub-system.

Hope that clarifies.
