Abstract
Described embodiments provide coherent processing of hash operations of a network processor having a plurality of processing modules. A hash processor of the network processor receives hash operation requests from the plurality of processing modules. A hash table identifier and bucket index corresponding to the received hash operation request are determined. An active index list is maintained for active hash operations for each hash table identifier and bucket index. If the hash table identifier and bucket index of the received hash operation request are in the active index list, the received hash operation request is deferred until the hash table identifier and bucket index corresponding to the received hash operation request clear from the active index list. Otherwise, the active index list is updated with the hash table identifier and bucket index of the received hash operation request and the received hash operation request is processed.
