Abstract
A method for transferring data from a general purpose register (GPR) to a vector register (VR), the method including vectorially combining data in the VR from the GPR, by executing instructions of a PowerPC Instruction Set Architecture (ISA), the step of combining including splatting a low nibble from the GPR into a low nibble in each element of a first VR by executing two 'load vector for shift left' (lvsl) or 'load vector for shift right' (lvsr) and one “vector subtract unsigned byte modulo” (vsububm), shifting a high nibble of the GPR into a low nibble the GPR, splatting the low nibble of the GPR into a low nibble in each element of a second VR by re-executing the two lvsl or lvsr and one vsububm instructions, shifting the low nibble of the second VR into a high nibble of the second VR and combining both first and second VRs into one VR.
