Web6 Sep 2003 · Upcoming processor generations increasingly provide instructions for sub-word parallelism. Thus, a parallel execution of 2, 4 or 8 instructions (add, sub) or of complex instructions (sum of differences) with an input of 2, 4 or 8 operand pairs becomes possible. The exploitation of sub-word parallelism is still weakly supported by current compilers. … WebExploiting Data Level Parallelism 33. Case Studies of Multicore Architectures I 34. Case Studies of Multicore Architectures II 35. ... The IEEE single precision floating point standard representation requires a 32 bit word, which may be represented as numbered from 0 to 31, left to right. The first bit is the sign bit, S, the next eight bits ...

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 WebSubword parallelism is an efficient and flexible solution for media processing because algorithm exhibit a great deal of data parallelism on lower precision data. It is also useful for computations unrelated to … WebSub-word parallelism in digital signal processing Abstract: We deal with parallelism at the data level.
