Abstract
A system and method are provided that permit an accurate checksum to be generated of a block of data being transmitted via a prefetched bus, despite repeated transmissions of identical portions of the block and presentation of those identical to checksum logic simultaneously with their transmission by the bus, by ensuring that only those portions of the data block that have yet to be checksummed are checksummed.
