Abstract: A computer system having patrol snoop sequencer that sequences through addresses of cache lines held in a higher level cache, making snoop reads using those addresses to a lower level cache. If a particular cache line held in the higher level cache is not held in the lower level cache, the particular cache line is identified as an eviction candidate in the higher level cache when a new cache line must be loaded into the higher level cache.

Abstract translation: 计算机系统具有巡视侦听序列器，该序列通过保持在较高级别缓存中的缓存行的地址进行排序，从而使窥探将这些地址读取到较低级别的缓存。 如果保持在较高级高速缓存中的特定高速缓存行没有保持在较低级高速缓存中，则当新高速缓存行必须被加载到较高级高速缓存中时，特定高速缓存行被标识为较高级高速缓存中的驱逐候选者。
