1. A vector processing engine (VPE) configured to in-flight reorder a resultant output vector data sample set generated by at least one execution unit executing a vector processing operation, comprising: at least one vector data file configured to: provide a fetched input vector data sample set in at least one input data flow path for a vector processing operation; and receive a reordered resultant output vector data sample set from at least one output data flow path to be stored; at least one execution unit provided in the at least one input data flow path, the at least one execution unit configured to: receive the input vector data sample set; and execute the vector processing operation on the input vector data sample set to provide a resultant output vector data sample set on the at least one output data flow path; and at least one reordering circuitry configured to: receive the resultant output vector data sample set on the at least one output data flow path; reorder the resultant output vector data sample set into the reordered resultant output vector data sample set without the resultant output vector data sample set being stored in the at least one vector data file; and provide the reordered resultant output vector data sample set on the at least one output data flow path.
