Web• Subword parallelism is an efficient and flexible solution for media processing. • The algorithm exhibit a great deal of data parallelism on lower precision data. • One key advantage of sub word parallelism is that it allows general purpose processors to exploit wider word sizes . Webelements packed into a single word. We call these packed data elements sub-words; accordingly, we use the term sub-word level parallelism1 (SLP) to refer to the fine-grained SIMD parallelism that these extensions were designed to exploit. While multimedia extensions can provide impressive performance increases on hand-tuned applications, the
