Abstract
In an embodiment, a method of handling data packets within a processor includes intercepting, by a hardware packet integrity checking module, one or more data fields associated with a current segment of a data packet being forwarded from a first hardware entity operating in a cut-through mode to one or more processing clusters, where at least one data field of the one or more data fields is indicative of an operation associated with the data packet. At the hardware error detection module, integrity of the current segment of the data packet is checked based on the one or more data fields and parameters corresponding to the operation associated with the data packet. At least one data field of the one or more data fields is modified upon detecting an integrity error. The data fields are forwarded to the one or more processing clusters.
