Delayed replacement of cache entries |
摘要 |
A cache entry replacement unit can delay replacement of more valuable entries by replacing less valuable entries. When a miss occurs, the cache entry replacement unit can determine a cache entry for replacement ("a replacement entry") based on a generic replacement technique. If the replacement entry is an entry that should be protected from replacement (e.g., a large page entry), the cache entry replacement unit can determine a second replacement entry. The cache entry replacement unit can "skip" the first replacement entry by replacing the second replacement entry with a new entry, if the second replacement entry is an entry that should not be protected (e.g., a small page entry). The first replacement entry can be skipped a predefined number of times before the first replacement entry is replaced with a new entry.
