Correlation detector

摘要

The invention is notably directed to a correlation detector comprising an input unit configured to receive a plurality of parallel data streams of discrete events. The correlation detector further comprises a memory array having a plurality of resistive memory elements. At least one resistive memory element is allocated to each of the parallel data streams. Furthermore, a programming array is provided comprising a plurality of programming elements. At least one programming element is allocated to each resistive memory element for applying a programming signal to the respective memory element. The correlation detector comprises further a control unit that is configured to control the programming signals as a function of a co-arrival characteristic of the discrete events. A correlation unit is configured to detect correlations between the received data streams based on resistance changes of the resistive memory elements. The invention further concerns a related method for detecting correlations.
