FPGA implementation of an optimized hybrid approximate multiplier using approximate parallel prefix adder R. Selvarasan, G. Sudhagar, K. Rasadurai Synergies in Smart and Virtual Systems Using Computational Intelligence, 2025 This paper presents the FPGA implementation of a highly optimized hybrid approximate multiplier designed using approximate parallel prefix adders (AxPPAs). The proposed design applies approximation selectively to the least significant bits (LSB) of hybrid adders, leveraging the strengths of Brent Kung and Kogge Stone architecture to balance accuracy, speed, and area efficiency. Experimental validation on an 8 × 8 multiplier reveals a 24.7% reduction in slice LUTs, a 16.7% reduction in occupied slices, and an 11.8% decrease in delay, while maintaining the same power consumption as exact designs. These results highlight the design’s effectiveness in achieving significant improvements in computational performance and hardware efficiency. The implementation is particularly suited for error-resilient applications such as signal processing, machine learning, and image processing. This work demonstrates the potential of AxPPA-based designs for modern VLSI systems requiring energy-efficient, high-speed, and low-area solutions.
An improved noise filter design for Canny edge detection with pipeline architecture K. Revathi, K. Rasadurai Security Issues in Communication Devices Networks and Computing Models Volume 2, 2025 The Canny edge detection algorithm stands out for its exceptional performance, but it is known to be intricate, time intensive, and demanding in terms of hardware resources. Moreover, existing implementations often employ a fixed set of threshold values for all images, failing to adapt to varying detection conditions and leading to suboptimal results. To address these challenges, this chapter proposes an enhanced version of the Canny algorithm. Using Sobel operator method and approximation techniques, it computes both magnitude and direction of the gradient, simplifying intricate calculations and reducing hardware requirements. Additionally, the algorithm incorporates Otsu's method to dynamically determine image thresholds. However, it is worth noting that Otsu's algorithm involves division operations, which can be computationally expensive and slow. This chapter introduces optimized pipeline architecture for the Canny edge detection algorithm deployed on an FPGA. The suggested method significantly enhances the algorithm's performance in comparison to the existing system's approach, specifically focusing on the FPGA device 7vx485tffg1157-3. The existing method, utilizing the conventional Canny edge detection algorithm with a pipeline architecture, achieved a delay period of 6.061ns (maximum frequency: 165.003MHz) and used 1,908 Slice LUTs on the FPGA device. In contrast, the proposed method improves upon these metrics by reducing the delay period to 3.897ns (maximum frequency: 156.614MHz) while requiring 889 Slice LUTs on the same FPGA device. This enhancement in performance is primarily attributed to the optimized pipeline architecture implemented in the proposed method. By streamlining data flow and computational stages, the proposed architecture showcases notable improvements in both speed and resource utilization without compromising the accuracy of edge detection.

The smart lighting system comprises node MCU, power supply, light-dependent resistor, LED driver, and LEDs, offering adaptive and energy-efficient lighting solutions. The smart plug, utilizing node MCU, power supply, Blink app, relay module, AC plug, and bulb, facilitates remote control and monitoring of electrical devices within the building. For controlled access, the smart gate integrates node MCU, power supply, Blink app, servo motor, and gate mechanism, enabling secure and automated entry/exit points. The smart energy meter, incorporating node MCU, voltage sensor, current sensor, energy meter, power supply, LDR circuit, 16 x 2 LCD display, relay module, and load (e.g., bulb), provides comprehensive energy usage insights for efficient resource management. The three applications are interconnected and managed through an IoT Blink app, enabling users to regulate and monitor functionalities remotely. Data visualization of the smart energy meter is facilitated through IoT UBIDOTS, offering intuitive graphical representations and analytics for efficient energy consumption within the building. This chapter details the architectural design, components, functionalities, and interconnectivity of the IoT-based SBMS applications, showcasing their collective role in promoting efficiency, security, and streamlined management within smart building infrastructures.
FPGA implementation of 256-bit Key AES algorithm using a modified S-box sharing algorithm J. V. Preethi, G. N. Kodandaramaiah, K. Rasadurai Security Issues in Communication Devices Networks and Computing Models Volume 2, 2025 This research introduces an optimized FPGA implementation of the advanced encryption standard (AES) algorithm using a 256-bit key. The use of an altered S-Box method in the AES encryption procedure is the main focus. The suggested methodology exhibits enhancements in significant performance metrics in contrast to the current strategy. The analysis specifically focuses on three important metrics: power consumption in milliwatts, latency in nanoseconds, and area usage measured in LUTs. The results show a little increase in LUT area use when comparing the suggested method to the current one, recording 520 LUTs as opposed to the prior 513. The suggested approach, on the other hand, achieves a notable reduction in latency, going from 66.579 nanoseconds in the conventional method to a mere 0.874 nanoseconds. Interestingly, power consumption for both approaches stays the same at 206.42 milliwatts. This study highlights the efficiency benefits that may be attained by utilizing a modified S-Box approach in the 256-bit key AES algorithm on Virtex 7 FPGA. Of particular note is the significant reduction in latency that can be achieved without sacrificing power consumption. These findings endorse the application of the proposed method to enhance AES encryption performance on FPGA-based devices.
Enhanced On-Chip Memory Reliability for Space Engineering using a Novel 2-Dimensional Error Detection and Correction Scheme Jenifer Shruthi J, K. Rasadurai 2024 International Conference on System Computation Automation and Networking Icscan 2024, 2024 The paper presents a novel error detection and correction (EDAC) scheme tailored for space engineering applications, which aims to enhance the reliability of on-chip memory under challenging environmental conditions, including cosmic radiation and extreme temperatures. The proposed 2-dimensional code employs a divide-symbol strategy, utilizing XOR operations to encode diagonal, parity, and check bits during the encoding process. The decoding process is sophisticated, incorporating syndrome calculation and region selection to effectively identify and rectify errors. Simulation results obtained using Xilinx Vivado demonstrates that the proposed scheme achieves low power consumption and minimal area utilization compared to existing methods. Specifically, the encoder exhibits a maximum and minimum delay of 128 endpoints, with resource utilization metrics showing 0.02% LUT, 0.03% FF, and 25% IO utilization. The decoder exhibits a maximum and minimum delay of 64 endpoints, with resource utilization metrics of 0.03% LUT, 0.02% FF, and 19% IO utilization. This innovative EDAC methodology offers a promising solution for improving memory reliability in space applications, particularly by addressing issues caused by multiple cell upsets induced by radiation. The scheme's advantages, including enhanced memory reliability, reduced power consumption, and minimal area utilization, position it as a potentially valuable tool for future space engineering projects.
Performance of MC-CDMA system thorough Turbo block codes K. Rasadurai, N. Kumaratharan 2nd International Conference on Electronics and Communication Systems Icecs 2015, 2015 Multi carrier code division multiple access (MC-CDMA) is an efficient multi carrier modulation (MCM) technique that mitigates problems like spectral limitation and distortion due to multipath channels. Nevertheless, in a high speed mobile communication channels the orthogonality among subcarriers are destroyed due to multipath fading. The loss of orthogonality can cause inter carrier interference (ICI) and multiple access interference (MAI). The effect of MAI reduces the system performance in term of bit error rate (BER). The Turbo block code (TBC) technique based low density parity check (LDPC) code is proposed to overcome the MAI. It provides better concatenated decoding scheme with lower complexity and higher efficiency for improving the performance of MC-CDMA system in terms of BER and the same is proved through simulation.
Performance enhancement of MC-CDMA system through novel sensitive bit algorithm aided turbo multi user detection Rasadurai Kumaravel, Kumaratharan Narayanaswamy Plos One, 2015 Multi carrier code division multiple access (MC-CDMA) system is a promising multi carrier modulation (MCM) technique for high data rate wireless communication over frequency selective fading channels. MC-CDMA system is a combination of code division multiple access (CDMA) and orthogonal frequency division multiplexing (OFDM). The OFDM parts reduce multipath fading and inter symbol interference (ISI) and the CDMA part increases spectrum utilization. Advantages of this technique are its robustness in case of multipath propagation and improve security with the minimize ISI. Nevertheless, due to the loss of orthogonality at the receiver in a mobile environment, the multiple access interference (MAI) appears. The MAI is one of the factors that degrade the bit error rate (BER) performance of MC-CDMA system. The multiuser detection (MUD) and turbo coding are the two dominant techniques for enhancing the performance of the MC-CDMA systems in terms of BER as a solution of overcome to MAI effects. In this paper a low complexity iterative soft sensitive bits algorithm (SBA) aided logarithmic-Maximum a-Posteriori algorithm (Log MAP) based turbo MUD is proposed. Simulation results show that the proposed method provides better BER performance with low complexity decoding, by mitigating the detrimental effects of MAI.
Performance enhancement of MC-CDMA system using LDPC codes K. Rasadurai, Parvathy S Kumar, N. Kumaratharan 2013 IEEE Conference on Information and Communication Technologies ICT 2013, 2013 A turbo block code (TBC) technique for improving the performance of a multi-carrier code division multiple access (MC-CDMA) system in terms of bit error rate (BER) is proposed in this paper. The objective of this work is to develop a coding scheme that generates low BER code-words. By implementing a time domain TBC, designed using powerful low density parity check (LDPC) code, the BER performance of MC-CDMA system is improved and the same is proved through simulation. Two types of LDPC codes, viz. random LDPC codes and quasi cyclic (QC) LDPC codes are analyzed. These codes also have error correction capability along with high performance efficiency in terms of BER. In addition a decoding algorithm with moderate decoding complexity and with feasible soft output generation is also proposed for each LDPC code.
Performance enhancement of MC-CDMA system through turbo multi-user detection K. Rasadurai, N. Kumaratharan 2012 International Conference on Computer Communication and Informatics Iccci 2012, 2012 In this paper turbo multi-user detection (MUD) technique is proposed for multi carrier code division multiple access (MC-CDMA) system to overcome the affects of multiple access interference (MAI) caused by the inter-cell and intra-cell interference and near far effect. The proposed technique estimates the interference from the unknown users and the interference estimate is subtracted from the received signal. Simulation results show that the turbo multi user detector significantly outperforms the conventional multi user detector for moderate and high signal-to-noise ratios.
