    • Efficient techniques are described for tracking a potential invalidation of a data cache entry in a data cache for which coherency is required. Coherency information is received that indicates a potential invalidation of a data cache entry. The coherency information in association with the data cache entry is retained to track the potential invalidation to the data cache entry. The retained coherency information is kept separate from state bits that are utilized in cache access operations. An invalidate bit, associated with a data cache entry, may be utilized to represents a potential invalidation of the data cache entry. The invalidate bit is set in response to the coherency information, to track the potential invalidation of the data cache entry. A valid bit associated with the data cache entry is set in response to the active invalidate bit and a memory synchronization command. The set invalidate bit is cleared after the valid bit has been cleared.
    • 描述了用于跟踪需要一致性的数据高速缓存中的数据高速缓存条目的潜在无效的高效技术。 一致性信息被接收,指示数据高速缓存条目的潜在无效。 与数据高速缓存条目相关联的一致性信息被保留以跟踪对数据高速缓存条目的潜在无效。 保留的一致性信息与在缓存访问操作中使用的状态位分开。 与数据高速缓存条目相关联的无效位可用于表示数据高速缓存条目的潜在无效。 响应于一致性信息设置无效位以跟踪数据高速缓存条目的潜在无效。 响应于活动无效位和存储器同步命令来设置与数据高速缓存条目相关联的有效位。 置位无效位在有效位清零后清零。
