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...
Quantum-dot Cellular Automata(QCA), a promising alternative to CMOS technology, can provide a powerful and efficient computing platform for image processing which has heavy computational requirements. Image thresholding is one such image processing technique that plays a significant role in applications of image segmentation for its intuitive properties and simplicity. This work proposes an efficient...
This work proposes a testable QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the Coupled Majority Minority (CMVMIN) QCA structure with the target to reduce wire crossings as well as the number of clock cycles required to operate a QCA circuit. The characterization of defects in such design leads to synthesis of a test block,...
Wire crossings limit the performance of a logic circuit in Quantum-Dot Cellular Automata (QCA) based design. Minimization of wire-crossings is, therefore, of prime importance in the current nanotechnology, susceptible to high error rates. This work proposes a QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the coupled Majority...
