In this paper, the implementation of DSP modules such as a floating point ALU are presented and designed. The design is based on high performance FPGA "STRATIX III". The implementation is done after functional and timing simulation. The simulation tool used is Model Sim. The tool for synthesis and implementation is QuartusII [2]. The experimental results shows the functional and timin...

The closed-loop stability issue of finite-precision realizations is investigated for digital controllers implemented in floating-point arithmetic. Unlike the existing methods which only address the effect of the mantissa bits in floating-point implementation to the sensitivity of closed-loop stability, the sensitivity of closed-loop stability is analyzed with respect to both the mantissa and ex...

Floating-point arithmetic provides a fast but inexact way of computing geometric predicates. In order for these predicates to be exact, it is important to rule out all the numerical situations where floating-point computations could lead to wrong results. Taking into account all the potential problems is a tedious work to do by hand. We study in this paper a floating-point implementation of a f...

The floating plaque in carotid artery is an uncommon condition that can be detected by a duplex ultrasonography scan and is a high-risk factor for embolic cerebrovascular disease. The histopathological features of floating plaque in carotid artery vary. To the best of our knowledge, there is still considerable controversy about the treatment of floating carotid plaque. In this case, the floatin...

While hardware/software partitioning has been shown to provide significant performance gains, most hardware/software partitioning approaches are limited to partitioning computational kernels utilizing integers or fixed point implementations. Software developers often initially develop an application using built-in floating point representations and later convert the application to a fixed point...

Given a vector of floating-point numbers with exact sum s, we present an algorithm for calculating a faithful rounding of s into the set of floating-point numbers, i.e. one of the immediate floating-point neighbors of s. If the s is a floating-point number, we prove that this is the result of our algorithm. The algorithm adapts to the condition number of the sum, i.e. it is very fast for mildly...

In this paper, we propose a balloon pump with floating valves to control the discharge flow rates of sample solutions. Because the floating valves were made from a photoreactive resin, the shapes of the floating valves could be controlled by employing different exposure patterns without any change in the pump configurations. Owing to the simple preparation process of the pump, we succeeded in c...

The purpose of this investigation was to prepare a gastro retentive drug delivery system of famotidine tablets. Floating tablets of famotidine were prepared employing lipid solid dispersion spray drying technique with gelucire 50/13 and compritol 888 along with HPMC K100M, lactose, sodium bicarbonate and citric acid. The floating tablets were evaluated for uniformity of weight, hardness, friabi...

This paper addresses the issue of Floating Quantifier phenomena in Hebrew, focusing on the case of the universal quantifier kol (‘all’) and proposes a new, non-derivational analysis in the LFG framework in which the floating and the non-floating quantifier constructions are treated separately. This is based on semantic evidence showing that the quantifiers in these constructions have non-identi...

The fused floating point add-subtract unit is useful for digital signal processing (DSP) applications Such as fast Fourier transform (FFT) & discrete cosine transform (DCT) butterfly operations. To improve the performance of fused floating point addsubtract unit, a dual path algorithm& pipelining algorithms are useful .The designs are implemented for both single and double precision. The fused ...
