“…Table 2 shows that the proposed design of the 8-bit adder has reduced 33% cell count, 5.3% area, and 65% delay as compared with the circuit in [47]. In addition, the cell count, area, and delay of the designed QCA D flip-flop are considerably improved compared to the QCA circuits in [21,[56][57][58], as listed in Table 3. Table 4 summarizes the comparative results, which indicates that the designed eight-bit PIPO exhibits considerable superiority over the existing in [21] in terms of cell count and area by 27% and 29%, respectively.…”

“…ese benefits can make the proposed QCA method useful for image processing applications applied on portable communication devices where low power consumption is demanded in today's world. Recently, some efforts have been made towards the design of QCA logic circuits for image processing applications such as MAC operation [20], BinDCT [21], image steganography [22], morphological edge detection [23], thresholding [24], noise removal [25], and morphological erosion and dilation [26]. e above scenario motivates us to investigate a new low-power DCT architecture based on QCA technology.…”

Optimization for power is one of the most important design objectives in modern digital image processing applications. The DCT is considered to be one of the most essential techniques in image and video compression systems, and consequently a number of extensive works had been carried out by researchers on the power optimization. On the other hand, quantum-dot cellular automata (QCA) can present a novel opportunity for the design of highly parallel architectures and algorithms for improving the performance of image and video processing systems. Furthermore, it has considerable advantages in comparison with CMOS technology, such as extremely low power dissipation, high operating frequency, and a small size. Therefore, in this study, the authors propose a multiplier-less DCT architecture in QCA technology. The proposed design provides high circuit performance, very low power consumption, and very low dimension outperform to the existing conventional structures. The QCADesigner tool has been utilized for QCA circuit design and functional verification of all designs in this work. QCAPro, a very widespread power estimator tool, is applied to estimate the power dissipation of the proposed circuit. The suggested design has 53% improvement in terms of power over the conventional solution. The outcome of this work can clearly open up a new window of opportunity for low power image processing systems.

This paper presents an optimized geometric greedy router (GGR) based on quantum dot cellular automata (QCA) technology. The proposed structure of GGR is based on a spanning tree of the network. This type of communication does not require an IP address. It uses only local information and can be used in many communication devices. In this paper, we first describe the principal components of the router and then we present their QCA architecture. The QCA technology is the most likely alternative to replace conventional circuits (CMOS) due to their very low power consumption and high processing speed. To consider integration with other complex circuit, we have utilized QCA clock-phase-based technique for the proposed design architecture. The results obtained using the QCA designer tool exhibit the superiority of the presented architecture over the existing designs. The proposed structure shows a reduction of 30% reduction in occupied space. The power dissipation rate of the proposed design is analyzed by QCAPro tool to approve its reliability.
