SYSTEM, APPARATUS AND METHOD FOR POWER LICENSE CONTROL OF A PROCESSOR

In one embodiment, a processor includes a current protection controller to: receive instruction width information and instruction type information associated with one or more instructions stored in an instruction queue prior to execution of the one or more instructions by an execution circuit; determine a power license level for the core based on the corresponding instruction width information and the instruction type information; generate a request for a license for the core corresponding to the power license level; and communicate the request to a power controller when the one or more instructions are non-speculative, and defer communication of the request when at least one of the one or more instructions is speculative. Other embodiments are described and claimed. 在一个实施例中，处理器包括电流保护控制器，用于：在由执行电路执行被存储在指令队列中的一个或多个指令之前，接收与该一个或多个指令相关联的指令宽度信息和指令类型信息；基于对应的指令宽度信息和指令类型信息，确定针对核心的功率许可水平；针对核心生成对许可的请求，该许可与功率许可水平相对应；以及当该一个或多个指令是非推测性的时，向功率控制器传送该请求，并且当该一个或多个指令中的至少一个指令是推测性的时，推迟对该请求的传送。描述了其他实施例并且要求保护这些实施例。
