Sub word parallelism

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.
