摘要： A system to improve error correction includes a fast decoder to process data packets until the fast decoder finds an uncorrectable error in a data packet at which point a request for at least two data packets is generated. The system also includes a slow decoder to correct the uncorrectable error in a data packet based upon the at least two data packets.

摘要： Techniques and articles of manufacture are provided comprising computer readable programs that, when executed on the computer, cause the computer to delete a leaf from a Patricia tree having a direct table and a plurality of PSCB's which decode portions of the pattern of a leaf in the tree without shutting down the functioning of the tree. A leaf having a pattern is identified as a leaf to be deleted. Using the pattern, the tree is walked to identify the location of the leaf to be deleted. The leaf to be deleted is identified and deleted, and any relevant PSCB modified, if necessary. The technique also is applicable to deleting a prefix of a prefix.

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： A method and apparatus are used for finding the longest prefix match in a variable length prefix search when searching a direct table within a routing table structure of a network processor. The search through the routing table structure is expedited by hashing a first segment of an internet protocol address with a virtual private network number followed by concatenating the unhashed bits of the IP address to the result of the hash operation to form an input key. Patterns are compared a bit at a time until an exact match or the best match is found. The search is conducted in a search tree that provides that the matching results will be the best possible match.

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.
