This paper presents a new data representation known as Dual FiXedpoint (DFX), which employs a single bit exponent to select two different fixedpoint scalings. DFX provides a compromise between conventional fixed-point and floating-point representations. It has the implementation complexity similar to that of a fixed-point system together with the improved dynamic range offered by a floating-poi...

SPRY061 System developers, especially those who are new to digital signal processors (DSPs), are sometimes uncertain whether they need to use fixedor floating-point DSPs for their systems. Both fixedand floating-point DSPs are designed to perform the highspeed computations that underlie real-time signal processing. Both feature system-ona-chip (SOC) integration with on-chip memory and a variety...

Management of infirmity through medication is entering a new era in which growing number of novel drug delivery systems are being employed and are available for therapeutic use. Oral sustained release gastro-retentive dosage forms (GRDFs) offer many advantages for drugs with absorption from upper parts of gastrointestinal tract and for those acting locally in the stomach, improving the bioavail...

Floating-point arithmetic is often seen as untrustworthy. We show how manipulating precisions according to the following rules of thumb enhances the reliability of and removes surprises from calculations: • Store data narrowly, • compute intermediates widely, and • derive properties widely. Further, we describe a typing system for floating point that both supports and is supported by these rule...

1 Linux is a popular operating system for embedded systems. Some embedded systems use processors without floating point accelerators (FPA) or floating point units (FPU), in order to satisfy cost and power consumption requirements. This paper describes and compares optimization options for software implementation of floating point operations on systems without FPA or FPU. Our results show that s...

The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the types of floating drug delivery systems, principal and mechanism of floatation to achieve gastric retention. Drug delivery systems are those that float immediately upon contact with gastric fluids present promising approaches for increasing the bioavailabili...

Objective: The main purpose of this study is to prepare a floating micro articulated drug delivery system of ciprofloxacin by using non-aqueous solvent evaporation technique to increase the bioavailability and therapeutic effectiveness of the drug by prolonging its gastric residence time. Methods: Floating microparticles were prepared by using different low-density polymers such as ethyl cellul...

Purpose. Effective Helicobacter pylori eradication requires delivery of the antibiotic locally in the stomach. High dose of amoxicillin (750 to 1000 mg) is difficult to incorporate in floating tablets but can easily be given in liquid dosage form. Keeping the above facts in mind, we made an attempt to develop a new floating in situ gelling system of amoxicillin with increased residence time usi...

Due to advancement of new technology in the field of VLSI and Embedded system, there is an increasing demand of high speed and low power consumption processor. Speed of processor greatly depends on its multiplier as well as adder performance. In spite of complexity involved in floating point arithmetic, its implementation is increasing day by day. Due to which high speed adder architecture beco...
