His work primarily focuses on systems and methods that enhance the efficiency of lookup circuits and hash functions.
Latest Patents
Among his latest patents, Chase has developed systems and methods for implementing low-latency lookup circuits using sparse hash functions. This innovative lookup circuit evaluates hash functions that map keys to addresses in lookup tables. The circuit includes multiple hash function sub-circuits, each applying a respective hash function to an input key value, producing a hash value. Each sub-circuit may multiply bit vectors representing key values by a sparse bit matrix and add a constant bit vector to the results. The design allows for very low latency in lookup operations, significantly improving performance.
Another notable patent involves generating bit matrices for hash functions using fast filtering. This system evaluates hash functions that map keys to addresses in lookup tables, similar to his previous work. Candidate pairs of hash functions are generated and tested for suitability in hashing a particular collection of keys. The suitability testing includes computing hash value bit vectors and determining whether the resulting hash value bit vectors belong to the same set through a modified union-find type operation.
