Abstract
Addition, search, and performance of other allied activities relating to keys are performed in a hardware hash table. Further, high performance and efficient design may be provided for a hash table applicable to CPU caches and cache coherence directories. Set-associative tables and cuckoo hashing are combined for construction of a directory table of a directory based cache coherence controller. A method may allow configuration of C cuckoo ways, where C is an integer greater than or equal to 2, wherein each cuckoo way Cis a set-associative table with N sets, where each set has an associativity of A, where A is an integer greater than or equal to 2.
