Algo-Logic Systems’ Ultra-Low-Latency (ULL) Exact Match Search Engine (EMSE) IP is latency-optimized key-value lookup system for accelerated finance applications. Algo-Logic’s EMSE core has the unique ability to maintain constant lookup time through an advanced table balancing algorithm input instead of a variable lookup delays due common with trees and/or hash probing algorithms.

The EMSE stores a value along with each entry/key whereas a typical lookup engine requires an additional memory lookup after a match address has been found. Therefore, value is returned along with the match without an extra memory lookup, thus reducing latency.

EMSE can be used either as a stand-alone FPGA IP using the hardware command interface or with an API so that data can be shared between software and logic on FPGA.
