摘要：
A computer system for instruction execution includes a processor having a pipeline. The system is configured to perform a method including fetching, in the pipeline, a plurality of instructions, wherein the plurality of instructions includes a plurality of branch instructions, for each of the plurality of branch instructions, assigning a branch uncertainty to each of the plurality of branch instructions, for each of the plurality of instructions, assigning an instruction uncertainty that is a summation of branch uncertainties of older unresolved branches and balancing the instructions, based on a current summation of instruction uncertainty, in the pipeline.
