Abstract
We demonstrate frequency-domain neural signal processing for linear weighted summation and non-linear ReLU activation, using a flexible interconnect to synthesize both sub-circuits. We show that neural network sub-circuits can drive each other without amplification and confirm a low <1.5% penalty in accuracy for concatenated operation.
