Abstract
The present manuscript deals with the realization of Processing In-memory (PIM) computing architecture using Quantum Dot Cellular Automata (QCA) and Akers array. The PIM computing architecture becomes popular due to its effective framework for storage and computation of data in a single unit. Here, we illustrate two input NAND and NOR gate with the help of QCA based Akers Array as a case study. The QCA flip-flop is used as a primitive cell to design PIM architecture. The results suggested that both the gate have minimum power dissipation. The polarization results of proposed architecture suggested that the signals are in good control. The foot print of the primitive cell equals to 0.04 micron^2, which is smaller than conventional CMOS primitive cell. The combination of QCA and Akers array provides many additional benefits over the conventional architecture like reduction in the power…
