根据指令提示改变从存储器检索的数据量

Varying an amount of data retrieved from memory based upon an instruction hint
摘要：
In at least one embodiment, a processor detects during execution of program code whether a load instruction within the program code is associated with a hint. In response to detecting that the load instruction is not associated with a hint, the processor retrieves a full cache line of data from the memory hierarchy into the processor in response to the load instruction. In response to detecting that the load instruction is associated with a hint, a processor retrieves a partial cache line of data into the processor from the memory hierarchy in response to the load instruction.

在至少一个实施例中，处理器在执行程序代码期间检测程序代码内的加载指令是否与提示相关联。 响应于检测到加载指令不与提示相关联，处理器响应于加载指令从存储器层次结构检索完整的高速缓存行数据到处理器。 响应于检测到加载指令与提示相关联，处理器响应于加载指令从存储器层次结构检索数据的部分高速缓存行到处理器中。
