Abstract: A DPE memristor crossbar array system includes a plurality of partitioned memristor crossbar arrays. Each of the plurality of partitioned memristor crossbar arrays includes a primary memristor crossbar array and a redundant memristor crossbar array. The redundant memristor crossbar array includes values that are mathematically related to values within the primary memristor crossbar array. In addition, the plurality of partitioned memristor crossbar arrays includes a block of shared analog circuits coupled to the plurality of partitioned memristor crossbar arrays. The block of shared analog circuits is to determine a dot product value of voltage values generated by at least one partitioned memristor crossbar array of the plurality of partitioned memristor crossbar arrays.

Abstract: Filters are represented as k-SAT solutions. A filter query includes a k-SAT clause having literals pertaining to variables. A ternary content-addressable memory (TCAM) has cells programmed in correspondence with the k-SAT solutions. Input column lines of the TCAM that correspond to variables to which the literals of the k-SAT clause pertain are set in accordance with inversions of the literals. Input column lines of the TCAM that correspond to variables to which no literal of the k-SAT clause pertains are set in accordance with a “don't care” state. Responsive to any output match row line of the TCAM being set, the filter query is indicated as failing to satisfy the filters. Responsive to no output match row line of the TCAM being set, the filter query is indicated as satisfying the filters.
