Abstract:

Today's architectures exploit long pipelines in order to increase instruction-level parallelism by grouping sets of consecutive instructions and feeding them into the pipeline with the purpose of executing them in a single cycle. The IBM Power architecture executes programs by dispatching groups of instructions where a dispatch group is f...More
