摘要：Microarchitecture policies and structures to predict execution clusters andfacilitate inter-cluster communication are disclosed. In disclosed embodiments,
sequentially ordered instructions are decoded into micro-operations. Execution of oneset of micro-operations is predicted to involve execution resources to perform memoryaccess operations and inter-cluster communication, but not to perform branchingoperations. Execution of a second set of micro-operations is predicted to involve
execution resources to perform branching operations but not to perform memory accessoperations. The micro-operations are partitioned for execution in accordance with thesepredictions, the first set of micro-operations to a first cluster of execution resources andthe second set of micro-operations to a second cluster of execution resources. The firstand second sets of micro-operations are executed out of sequential order and areretired to represent their sequential instruction ordering.
