    摘要： A method and system for prefetching in computer system are provided. The method in one aspect includes using a prefetch engine to perform prefetch instructions and to translate unmapped data. Misses to address translations during the prefetch are handled and resolved. The method also includes storing the resolved translations in a respective cache translation table. A system for prefetching in one aspect includes a prefetch engine operable to receive instructions to prefetch data from the main memory. The prefetch engine is also operable to search cache address translation for prefetch data and perform address mapping translation, if the prefetch data is unmapped. The prefetch engine is further operable to prefetch the data and store the address mapping in one or more cache memory, if the data is unmapped.

    摘要翻译： 提供了一种在计算机系统中预取的方法和系统。 该方法在一个方面包括使用预取引擎来执行预取指令并转换未映射的数据。 在预取期间解决翻译错误的处理和解决。 该方法还包括将分辨的翻译存储在相应的缓存转换表中。 用于在一个方面预取的系统包括预取引擎，其可操作以接收从主存储器预取数据的指令。 如果预取数据未被映射，则预取引擎还可用于搜索缓存地址转换以获取预取数据并执行地址映射转换。 如果数据未被映射，则预取引擎还可操作以预取数据并将地址映射存储在一个或多个高速缓冲存储器中。

    摘要： A method for reconfiguring a cache memory is provided. The method in one aspect may include analyzing one or more characteristics of an execution entity accessing a cache memory and reconfiguring the cache based on the one or more characteristics analyzed. Examples of analyzed characteristic may include but are not limited to data structure used by the execution entity, expected reference pattern of the execution entity, type of an execution entity, heat and power consumption of an execution entity, etc. Examples of cache attributes that may be reconfigured may include but are not limited to associativity of the cache memory, amount of the cache memory available to store data, coherence granularity of the cache memory, line size of the cache memory, etc.
