  • Pipelined database processing circuit and method
    Patent number: 10482129
    Abstract: Disclosed approaches for accessing data involve determining in a first stage of a pipelined processing circuit, hash values from keys in a data access request and determining in a second stage of the pipelined processing circuit and from a hash table, addresses associated with the hash values. In a third stage of the pipelined processing circuit, data are read at the addresses in a memory arrangement, and in a fourth stage of the pipelined processing circuit a subset of the data read from the memory arrangement is selected according to a query in the data access request. In a fifth stage of the pipelined processing circuit, the subset of the data read from the memory arrangement is merged into response data.
