Abstract: A processor includes a core to execute instructions and a cache memory coupled to the core and having a plurality of entries. Each entry of the cache memory may include a data storage including a plurality of data storage portions, each data storage portion to store a corresponding data portion. Each entry may also include a metadata storage to store a plurality of portion modification indicators, each portion modification indicator corresponding to one of the data storage portions. Each portion modification indicator is to indicate whether the data portion stored in the corresponding data storage portion has been modified, independently of cache coherency state information of the entry. Other embodiments are described as claimed.

Abstract translation: 处理器包括执行指令的核心和耦合到核心并且具有多个条目的高速缓存存储器。 高速缓冲存储器的每个条目可以包括包括多个数据存储部分的数据存储部分，每个数据存储部分存储对应的数据部分。 每个条目还可以包括用于存储多个部分修改指示符的元数据存储器，每个部分修改指示符对应于数据存储部分之一。 每个部分修改指示符用于指示存储在相应的数据存储部分中的数据部分是否已被修改，而与条目的高速缓存一致性状态信息无关。 其他实施例被描述为所要求保护的。
