System, apparatus, and method for prefetching physical pages in processor

The disclosure relates to systems, apparatuses, and methods for prefetching physical pages in a processor. In one embodiment, a processor includes: one or more execution circuitry to execute instructions; a stream prediction circuit coupled to the one or more execution circuits, the stream prediction circuit to receive a demand request for the information, and to generate a page prefetch prompt for the first page based at least in part on the demand request; and a prefetcher circuit to generate first prefetch requests, each first prefetch request for a cache line, the flow prediction circuit being decoupled from the prefetcher circuit. Other embodiments are described and claimed. 本公开涉及用于在处理器中预取物理页的系统、装置和方法。在一个实施例中，一种处理器包括：一个或多个执行电路，用于执行指令；流预测电路，与一个或多个执行电路相耦合，该流预测电路用于接收针对信息的需求请求，并且至少部分基于需求请求，来生成针对第一页的页预取提示；以及预取器电路，用于生成第一预取请求，每个第一预取请求针对一缓存线，流预测电路与预取器电路解耦。描述和要求保护了其他实施例。
