Apparatus and method for managing errors on a point-to-point interconnect

One embodiment of the present invention provides a system for facilitating error management on a point-to-point interconnect within a system. The system includes the point-to-point interconnect, a source of data transactions coupled to the point-to-point interconnect, and a destination of data transactions coupled to the point-to-point interconnect. A transmitting mechanism at the source transmits data transactions to the destination across the point-to-point interconnect. A receiving mechanism at the destination receives these data transactions from the point-to-point interconnect. The apparatus also includes a synchronizing mechanism that is configured to synchronize the source and destination. A local buffer at the source stores a copy of each data transaction that is transmitted from the source. A detecting mechanism at the destination is used to detect failed data transactions using any method useful for detecting failed data transactions, for example, parity, cyclic redundancy code, error correcting code, and the like
