| Abstract: | In this paper, a technology named SoftSIMD is introduced to achieve the speedup of parallel computing between high and low subwords of the register in the processors that do not have the Single Instruction Multiple Data(SIMD) extensions. The technologies include addition and subtraction operations, multiplication and dot product operations. On the basis of the recent research, it discusses the negative operands in the dot product operations originally, and applies the SoftSIMD technology to the complex operations, which make it more adapted to the applications in the field of Digital Signal Processing(DSP). |
