Abstract:

An integrated-circuit neural network includes chain of multiply-accumulate units co-located with a high-bandwidth storage array. Each multiply accumulate includes a digital input port, analog input port and multiply-adder circuitry. The digital input port receives a matrix of digital-weight values from the storage array and the analog input port receives a counterpart matrix of analog input signals, each analog input signal exhibiting a respective electronic current representative of input value. The multiply-adder circuitry generates a matrix of analog output signals by convolving the matrix of digital-weight values with the matrix of analog input signals including, for each analog output signal within the matrix of analog output signals, switchably enabling weighted current contributions to the analog output signal based on logic states of on respective bits of one or more of the digital-weight values.
