Abstract
A method and circuit for performing multi-layer vector-matrix multiplication operations may include, at a first multiplier-accumulator (MAC) layer, converting a digital input vector using one-bit digital to analog converters (DACs); sequentially performing vector-matrix multiplication operations for the analog DAC signals; and sequentially performing an analog-to-digital (ADC) operation on outputs of the vector-matrix multiplication operations to generate binary partial output vectors. At a second MAC layer, the method and circuit may sequentially receive the binary partial output vectors from the first MAC layer at multi-bit DACs; and sequentially perform vector-matrix multiplication operations to generate a summed binary output for the second MAC layer.
