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...

Formal and informal modifications to the US-Japan Alliance have expanded value operational structure delivers in support of US Japanese national combined naval activities Southeast Asia. This article analyzes how now serves as an increasingly powerful force multiplier which magnifies capabilities, efficiency, impact two allies’ Unlike previous studies on role United States or Japan region, it f...

The Bogomolov multiplier is a group theoretical invariant isomorphic to the unramified Brauer group of a given quotient space. We derive a homological version of the Bogomolov multiplier, prove a Hopf-type formula, find a five term exact sequence corresponding to this invariant, and describe the role of the Bogomolov multiplier in the theory of central extensions. A new description of the Bogom...

The floating-point multiplication is one of the most basic and frequent digital signal processing operations, and its accuracy and throughput greatly decide the overall accuracy and throughput of the digital signal processors. Based on vectorizing a conventional double precision multiplier, we propose a multiple precision floating-point multiplier. It supports either one double precision multip...

A bit parallel systolic multiplier in the finite field GF(2) over the polynomial basis where irreducible polynomial generate the field GF(2) is presented. The complexity of the proposed multiplier is compared in terms of area, latency and speed. The proposed multiplier has high throughput as compared with the traditional systolic multiplier. Moreover, this multiplier is highly regular, modular,...

In this paper we describe an efficient implementation of an IEEE 754 single precision floating point multiplier targeted for Xilinx Virtex-5 FPGA. VHDL is used to implement a technology-independent pipelined design. The multiplier implementation handles the overflow and underflow cases. Rounding is not implemented to give more precision when using the multiplier in a Multiply and Accumulate (MA...

This paper investigates the problem of frequencyweighted l2-sensitivity minimization subject to l2-scaling constraints for two-dimensional (2-D) state-space digital filters described by the Roesser model. It is shown that the FornasiniMarchesini second model can be imbedded in the Roesser model. Two iterative methods are developed to solve the constrained optimization problem encountered. The f...
