Abstract: Embodiments of the present invention disclose a method for accessing a cache and a pseudo cache agent (PCA). The method of the present invention is applied to a multiprocessor system, where the system includes at least one NC, at least one PCA conforming to a processor micro-architecture level interconnect protocol is embedded in the NC, the PCA is connected to at least one PCA storage device, and the PCA storage device stores data shared among memories in the multiprocessor system. The method of the present invention includes: if the NC receives a data request, obtaining, by the PCA, target data required in the data request from the PCA storage device connected to the PCA; and sending the target data to a sender of the data request. Embodiments of the present invention are mainly applied to a process of accessing cache data in the multiprocessor system.

Abstract translation: 本发明的实施例公开了一种用于访问高速缓存和伪高速缓存代理（PCA）的方法。 本发明的方法应用于多处理器系统，其中系统包括至少一个NC，至少一个符合处理器微架构级互连协议的PCA嵌入在NC中，PCA连接到至少一个 PCA存储装置，PCA存储装置将存储在多处理器系统中的数据共享。 本发明的方法包括：如果NC接收到数据请求，则由PCA从连接到PCA的PCA存储设备获得数据请求中所需的目标数据; 并将目标数据发送到数据请求的发送者。 本发明的实施例主要应用于在多处理器系统中访问高速缓存数据的过程。
