1. A method, in a data processing system, for performing a matrix multiplication operation, comprising: performing a vector load operation to load a first vector operand of the matrix multiplication operation to a first target vector register of the data processing system: performing a load and splat operation to load an element of a second vector operand and replicating the element to each of a plurality of elements of a second target vector register of the data processing system; performing a multiply add operation on elements of the first target vector register and elements of the second target vector register to generate a partial product of the matrix multiplication operation; and accumulating the partial product of the matrix multiplication operation with other partial products of the matrix multiplication operation, wherein a reorganization of data is performed by the load and splat operation and the accumulation of the partial product of the matrix multiplication operation with other partial products of the matrix multiplication operation is performed without issuing a separate register to register operation via an issue slot.
