数据高速缓冲存储器预取提示
摘要：
本公开提供了一种使用预取提示的方法和装置。所述方法的一个实施方案包括：在与第一高速缓冲存储器(120)相关联的第一预取器(150)处，绕过发出对从所述第一预取器确定的存储器地址序列中的一定数目的存储器地址预取数据的请求。所述数目被指示在从与第二高速缓冲存储器(125)相关联的第二预取器(140)接收的请求中。所述方法的这个实施方案还包括从所述第一预取器发出对从所绕过的存储器地址后的存储器地址预取数据的请求。
摘要（英）：

The present disclosure provides a method and apparatus for using prefetch hints. One embodiment of the method includes bypassing, at a first prefetcher (150) associated with a first cache (120), issuing requests to prefetch data from a number of memory addresses in a sequence of memory addresses determined by the first prefetcher. The number is indicated in a request received from a second prefetcher (140) associated with a second cache (125). This embodiment of the method also includes issuing, from the first prefetcher, a request to prefetch data from a memory address subsequent to the bypassed memory addresses.
