Zusammenfassung:A computer-implemented method, computer program product, and computer processing system are provided. The method includes processing, by a superscalar processing pipeline, respective sets of instructions in respective instruction processing cycles using an Instruction Completion Table (ICT) with a Ready-To-Complete (RTC) vector. The ICT includes a plurality of entries, each corresponding to a respective one of the instructions. A Next-To-Complete (NTC) instruction from among the respective sets of instructions is computed using the RTC vector.
