A cyclic redundancy code (CRC) and optionally a syndrome value calculation of one or more implantable medical device (IMD) data block is conducted by block mover/reader hardware of the IMD when the data block(s) are moved and/or read. In the block read operation, each data byte or word in the block mover data register is read in a first clock cycle. In the block move operation, each data byte is read in the first clock cycle in this way and then moved to a destination register in a second clock cycle. The data CRC and optionally the syndrome value accumulate in the CRC and syndrome registers as all data bytes of the data block(s) are read in the first clock cycle. When the last data byte or word of the data block(s) is sequentially read (and moved in the block move operation), the accumulated data CRC and syndrome value are either stored as the associated data CRC and optional syndrome value or are used for comparison with a previously stored data CRC and optional syndrome value associated with the data block(s) in the comparison operation to determine if the data block(s) is corrupted.
