Hash table lookup engine
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
Cuckoo or d-left hash table engine with CRC and Toeplitz hash functions, insert, delete and lookup, for flow tables and key-value caches.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
