Approaches for maximizing throughput of self-timed multiply-accumulate units (MACs) are developed and assessed using the NULL Convention Logic (NCL) paradigm. In this class of self-timed circuits, the functional correctness is independent of any delays in circuit elements, through circuit construction, and independent of any wire delays, through the isochronic fork assumption [1, 2], where wire delays are assumed to be much less than gate delays. Therefore self-timed circuits provide distinct… CONTINUE READING
