![]() The RapidIO specification defines both input and output error detection and recovery state machines that include handshaking protocols in which the receiving end signals that an error is detected by sending a packet-not-accepted control symbol, the transmitter then sends an input-status link-request control symbol to which the receiver responds with a link-response control symbol to indicate which packet requires transmission. The RapidIO II IP core Physical layer transparently manages these errors for you. The receiver checks the CRC of the received control symbols and packets.The receiver detects control characters changed into data characters or data characters changed into control characters, based on the context in which the character is received.The receiver checks the validity of the received 8B10B encoded characters, including the running disparity. ![]() The following mechanisms exist for checking and detecting errors: Transmission errors can be caused by noise on the line and consist of one or more bit errors.
