Abstract: Techniques are provided for executing a vector alignment instruction. A scalar register file in a first processor is configured to share one or more register values with a second processor, the one or more register values accessed from the scalar register file according to an Rt address specified in a vector alignment instruction, wherein a start location is determined from one of the shared register values. An alignment circuit in the second processor is configured to align data identified between the start location within a beginning Vu register of a vector register file (VRF) and an end location of a last Vu register of the VRF according to the vector alignment instruction. A store circuit is configured to select the aligned data from the alignment circuit and store the aligned data in the vector register file according to an alignment store address specified by the vector alignment instruction.
