High-Speed Energy-Efficient Fixed-Point Signed Multipliers for FPGA-Based DSP Applications

Project Code :TVMAFE638

Objective

The project is to design and optimize fixed-point signed multipliers for use in digital signal processing (DSP) on FPGA platforms. The focus will be on achieving high-speed operation while minimizing energy consumption.

Abstract

Digital Signal Processing (DSP) applications such as image processing, wireless communication, and real-time data analytics require high-performance arithmetic units that can operate efficiently within strict energy constraints. Multipliers, being one of the most critical components, directly impact the speed, power consumption, and area utilization of FPGA-based systems. Conventional signed multipliers often suffer from trade-offs between high speed and energy efficiency, limiting their suitability for low-power, high-throughput applications. This work presents the design and analysis of high-speed, energy-efficient fixed-point signed multipliers optimized for FPGA implementation. The proposed architecture leverages efficient partial product reduction techniques and parallel processing strategies to minimize critical path delay while reducing dynamic power dissipation. Comparative analysis with conventional multiplier designs highlights significant improvements in throughput, energy-per-operation, and resource utilization. The results demonstrate that the proposed multipliers not only achieve faster computation speeds but also provide enhanced energy efficiency, making them highly suitable for next-generation DSP applications in portable and real-time embedded systems.
