Abstract: Methods and apparatuses for releasing the sticky state of cache lines for one or more group IDs. A sticky removal engine walks through the tag memory of a system cache looking for matches with a first group ID which is clearing its cache lines from the system cache. The engine clears the sticky state of each cache line belonging to the first group ID. If the engine receives a release request for a second group ID, the engine records the current index to log its progress through the tag memory. Then, the engine continues its walk through the tag memory looking for matches with either the first or second group ID. The engine wraps around to the start of the tag memory and continues its walk until reaching the recorded index for the second group ID.

Abstract translation: 用于释放一个或多个组ID的高速缓存行粘性状态的方法和设备。 粘性删除引擎遍历系统缓存的标签内存，寻找与第一组ID相匹配的第一组ID，该ID将从系统缓存中清除其缓存行。 引擎清除属于第一组ID的每个缓存行的粘滞状态。 如果引擎收到第二组ID的释放请求，则引擎会记录当前索引以通过标签内存记录其进度。 然后，引擎继续浏览标签内存，查找与第一组或第二组ID相匹配的内容。 引擎回卷到标签内存的开始位置，继续走路，直到达到第二组ID的已记录索引。

Abstract translation: 用于释放用于一个或多个组ID的高速缓存行的粘性状态的方法和装置。 粘性移除引擎遍历系统缓存的标签存储器，寻找与从系统高速缓存清除其高速缓存行的第一组ID的匹配。 引擎清除属于第一组ID的每条缓存线的粘性状态。 如果引擎接收到第二组ID的释放请求，则引擎记录当前索引以通过标记存储器记录其进度。 然后，引擎继续穿过标签内存，寻找与第一或第二组ID的匹配。 发动机绕包到标签存储器的开头，并继续其行进直到到达第二组ID的记录索引。
