Data bus with automatic data integrity verification and verification method

摘要

A data bus system with data integrity verification is arranged so that a bus device receiving a message always responds by sending a check sequence back to the message originating device; i.e., a check sequence is automatically returned to a message originating device as part of every bus transaction. The originating device reads the returned check sequence and uses it to verify the integrity of the data transferred between the two devices. The check sequence can be created by the receiving device based on the data conveyed, or the receiving device can simply echo back a check sequence that is appended to the incoming data.
