摘要： Embodiments of apparatuses, methods, and systems for adaptive dynamic dispatch of micro-operations are disclosed. In an embodiment, an apparatus includes a plurality of redundant execution units, a dispatcher, control hardware, a first counter, and a second counter. The dispatcher is to dispatch micro-operations to one or more of the plurality of redundant execution units, the micro-operations having a plurality of micro-operation types. The first counter to generate a first count of dispatches, during a window, of micro-operations having a first type of the plurality of micro-operation types. The second counter to generate a second count of dispatches, during the window, of micro-operations having any type of the plurality of micro-operation types. The control hardware is to cause a switch between a first mode and a second mode based in part on the first count and the second count. In the first mode, the dispatcher is to dispatch micro-operations having the first type to only a subset of the plurality of redundant execution units. In the second mode, the dispatcher is to dispatch micro-operations having the first type to all of the plurality of redundant execution units.
