Abstract:

A method for performing hash code calculations may include calculating, during a write operation for a data block, a hash code for an occupied portion of the data block, inserting, during the write operation, a marker into the data block, calculating, during a read operation for the data block, a hash code for the occupied portion of the data block, searching, during the read operation, for the marker in the data block, and terminating the hash code calculation in response to finding the marker. A system may include a first interface configured to receive data blocks, a second interface configured to transmit data blocks, and hash logic coupled between the first and second interfaces, wherein the hash logic is configured to calculate a hash code for the occupied portion of a data block received through the first interface, and insert a marker in an unoccupied portion of the data block.
