Multiple independent-gate field effect transistors (MIGFETs) have great potential for digital integrated circuits. In this work, we demonstrate that conventional binary adder architectures may benefit from the use of MIGFET devices. As case studies, we have designed ripple-carry adders (RCA) and parallel-prefix adders (PPA), where circuit area and performance optimizations are explored. Different...
This work presents an efficient algorithm to obtain a material implication (IMPLY) expression from a sum-of-products (SOP). The resulting expression is computable with two work memristors. The proposed method has linear time complexity with respect to the SOP size. Comparison to previous work shows a reduction on the average number of IMPLY operations when applying the proposed method.
This paper proposes the utilization of factored forms in logic synthesis for memristive material implication stateful logic. Factored forms have not been explored by previous works due to expected increasing on device count. We present an algorithm to obtain factored forms computable with minimum number of memristors. Comparison to previous works shows an average reduction of 12% in the number of...
This paper presents two contributions to logic synthesis for memristive stateful logic. Firstly, we demonstrate the necessity to correct results provided by existing logic synthesis methods to ensure the expected computation. Secondly, we propose the concept of multi-memristor implication as a generalization of multi-input implication. Experimental results have shown a reduction of 6.5% in the number...
This work proposes the use of non-recursive factored forms in material implication logic as a way to increase performance with a small additional cost in the number of required devices. Previous works addressing memristor based implication logic focus only on recursive forms. The utilization of factored forms can reduce the number of operations. Since this kind of logic is naturally sequential, the...
