A Processing in Memory Realization Using Quantum Dot Cellular Automata (QCA): Proposal and Implementation

Abstract

Processing in Memory (PIM) is a computing paradigm that promises enormous gain in processing speed by eradicating latencies in the typical von Neumann architecture. It has gained popularity owing to its throughput by embedding storage and computation of data in a single unit. We portray implementation of Akers array architecture endowed with PIM computation using Quantum-dot Cellular Automata (QCA). We present the proof of concept of PIM with its realization in the QCA designer paradigm. We illustrate implementation of Ex-OR gate with the help of QCA based Akers Array and put forth many interesting potential possibilities.

Bipolar resistive switching and memristive properties of hydrothermally synthesized TiO2 nanorod array: Effect of growth temperature

“…There are many possible solutions emerging in recent years to improve the performance metrics of computing systems. The brain-inspired neuromorphic computing architecture [3] and in-memory computing architecture [4][5] are two examples. Recently, the memristive device has emerged as a potential candidate to replace the flash-based memories [6][7] and also work as a basic building block for neuromorphic computing applications [8][9].…”

Realization of processing In-memory computing architecture using Quantum Dot Cellular Automata

“…In our previous study, we have constructed PIM architecture by employing QCA multiplexer [8]. In the QCA multiplexer based PIM architecture, there is less control on signal.…”
