Özet

This study presents an optimization algorithm for multiplexer (MUX)-based scaled addition for stochastic computing (SC). Accumulation operation can be performed in SC using a MUX unit. Cascaded structures of 2m-to-1 MUXs are used for the accumulation of multiple terms. Optimizing these designs holds significance in cases of accumulating a large number of inputs. The depth of the cascaded MUXs varies with m, affecting the hardware cost, delay, and accuracy. The proposed algorithm performs stage-wise optimization of m. Evaluation results show a lower hardware cost and a higher accuracy compared to the standard MUX-based SC addition using 2-to-1 MUXs for SC-based neural networks.
