Abstract:
A dot product multiplier for matrix operations for an A matrix of order 1×m with a coefficient B matrix of order m×m. Processing Elements (PEs) are arranged in an m×m array, the columns of the array summed to provide a dot product result. Each of the PEs contains a sign determiner and a plurality of analog multiplier cells, one multiplier cell for each value bit. The multipliers operate over four clock cycles, initializing a capacitor charge according to sign on a first clock phase, sharing charge on a second phase, canceling charge on a third phase, and outputting the resultant charge on a fourth phase, the resultant charge on each column representing the dot product for that column.
