    • Embodiments of the invention intelligently associate processes with core processors in a multi-core processor. The core processors are asymmetrical in that the core processors support different features or provide different resources. The features or resources are published by the core processors or otherwise identified (e.g., via a query). Responsive to a request to execute an instruction associated with a thread, one of the core processors is selected based on the resource or feature supporting execution of the instruction. The thread is assigned to the selected core processor such that the selected core processor executes the instruction and subsequent instructions from the assigned thread. In some embodiments, the resource or feature is emulated until an activity limit is reached upon which the thread assignment occurs.
    • 本发明的实施例在多核处理器中智能地将过程与核心处理器相关联。 核心处理器是不对称的,因为核心处理器支持不同的功能或提供不同的资源。 特征或资源由核心处理器发布或以其他方式识别(例如,经由查询)。 响应于执行与线程相关联的指令的请求,基于支持指令执行的资源或特征来选择核心处理器之一。 该线程被分配给所选择的核心处理器,使得所选择的核心处理器从分配的线程执行指令和后续指令。 在一些实施例中,资源或特征被模拟,直到到达发生线程分配的活动限制。
