This paper presents the design and implementation of signed-unsigned Modified Booth Encoding (SUMBE) multiplier. The present Modified Booth Encoding (MBE) multiplier and the Baugh-Wooley multiplier perform multiplication operation on signed numbers only. The array multiplier and Braun array multipliers perform multiplication operation on unsigned numbers only. Thus, the requisite of the modern ...

The paper presents FPGA implementation of a spectral sharpening process suitable for speech enhancement and noise reduction algorithms for digital hearing aids. Booth and Booth Wallace multiplier is used for implementing digital signal processing algorithms in hearing aids. VHDL simulation results confirm that Booth Wallace multiplier is hardware efficient and performs faster than Booth’s multi...

In this era, network security is becoming a great concern .Cryptography offers high security for communication and networking. Elliptic Curve Cryptography is gaining attraction with their high level of security with low cost, small key size and smaller hardware realization. Elliptic curve scalar multiplication is the most important operation in elliptic curve cryptosystems This paper develops a...

The development of Digital Signal Processors (DSPs), graphical systems, Field Programmable Gate Arrays (FPGAs)/ Application-Specific Integrated Circuits (ASICs), and multimedia systems all rely heavily on digital circuits. need for high-precision fixed-point or floating-point multipliers suitable Very Large-Scale Integration (VLSI) implementation in high-speed DSP applications is developing rap...

Abstract—In this paper, a novel Chinese abacus multiplier is presented. The architecture of a 4-bit multiplier is demonstrated. The simulation results of our work are compared with the 4-bit Braun array multiplier. The 0.35μm and 0.18μm TSMC CMOS technologies are used in the simulation. The delay time of the abacus multiplier is at least 63% less than that of Braun array multiplier for 0.18μm t...

Physical limitations of Complementary Metal-Oxide-Semiconductors (CMOS) technology at nanoscale and high cost of lithography have provided the platform for creating Quantum-dot Cellular Automata (QCA)-based hardware. The QCA is a new technology that promises smaller, cheaper and faster electronic circuits, and has been regarded as an effective solution for scalability problems in CMOS technolog...

Almost multiplier is rather a new concept in the theory of almost functions. In this paper we discussion the boundedness of almost multipliers on some special Banach algebras, namely stable algebras. We also define an adjoint and extension for almost multiplier.

Digital multipliers are most widely used component in applications such as convolution, Fourier transform, discrete cosine transforms, and digital filtering. Because outturn of these applications mainly depends on multiplier speed, therefore multipliers must be designed efficiently. In the proposed architecture, a variable-latency multiplier design with novel AHL architecture and a razor flip f...
