    • The present invention provides alignment and ordering of vector elements for SIMD processing. In the alignment of vector elements for SIMD processing, one vector is loaded from a memory unit into a first register and another vector is loaded from the memory unit into a second register. The first vector contains a first byte of an aligned vector to be generated. Then, a starting byte specifying the first byte of an aligned vector is determined. Next, a vector is extracted from the first register and the second register beginning from the first bit in the first byte of the first register continuing through the bits in the second register. Finally, the extracted vector is replicated into a third register such that the third register contains a plurality of elements aligned for SIMD processing. In the ordering of vector elements for SIMD processing, a first vector is loaded from a memory unit into a first register and a second vector is loaded from the memory unit into a second register. Then, a subset of elements are selected from the first register and the second register. The elements from the subset are then replicated into the elements in the third register in a particular order suitable for subsequent SIMD vector processing.
    • 本发明提供用于SIMD处理的向量元素的对准和排序。 在用于SIMD处理的向量元素的对齐中,一个向量从存储器单元加载到第一寄存器中,另一个向量从存储器单元加载到第二寄存器中。 第一个向量包含要生成的对齐向量的第一个字节。 然后,确定指定对齐向量的第一个字节的起始字节。 接下来,从第一寄存器提取向量,并且从第一寄存器的第一字节的第一位开始的第二寄存器继续通过第二寄存器中的位。 最后,将所提取的矢量复制到第三寄存器中,使得第三寄存器包含对准用于SIMD处理的多个元素。 在用于SIMD处理的向量元素的排序中,将第一向量从存储器单元加载到第一寄存器中,并且将第二向量从存储器单元加载到第二寄存器中。 然后,从第一寄存器和第二寄存器中选择元件的子集。 然后将来自子集的元素以适合于随后的SIMD向量处理的特定顺序复制到第三寄存器中的元素中。
