    摘要： A cache memory includes a cache array including a plurality of congruence classes each containing a plurality of cache lines, where each cache line belongs to one of multiple classes which include at least a first class and a second class. The cache memory also includes a cache directory of the cache array that indicates class membership. The cache memory further includes a cache controller that selects a victim cache line for eviction from a congruence class. If the congruence class contains a cache line belonging to the second class, the cache controller preferentially selects as the victim cache line a cache line of the congruence class belonging to the second class based upon access order. If the congruence class contains no cache line belonging to the second class, the cache controller selects as the victim cache line a cache line belonging to the first class based upon access order.

    摘要翻译： 高速缓存存储器包括包含多个等同类的高速缓存阵列，每个级别包含多条高速缓存行，其中每条高速缓存行属于至少包括第一类和第二类的多个类中的一个。 缓存存储器还包括指示类成员资格的高速缓存阵列的高速缓存目录。 高速缓冲存储器还包括高速缓存控制器，其选择用于从同余类驱逐的受害缓存行。 如果同余类包含属于第二类的高速缓存行，则高速缓存控制器基于访问顺序优先选择属于第二类的同余类的高速缓存行作为受害缓存行。 如果同余类不包含属于第二类的高速缓存行，则高速缓存控制器基于访问顺序选择属于第一类的高速缓存行作为受害缓存行。

    摘要： The present invention relates to a system and computer-readable medium for storing a plurality of multi-field classification rules in a computer system. Each multi-field classification rule includes a rule specification that itself includes a plurality of fields and a plurality of field definitions corresponding to the fields. The method of the present invention includes providing a virtual rule table, where the table stores a plurality of field definitions, and for each of the plurality of multi-field classification rules, compressing the rule specification by replacing at least one field definition with an associated index into the virtual rule table. The method also includes storing each of the compressed rule specifications and the virtual rule table in a shared segment of memory.
