Multimedia and communication algorithms from the embedded system domain often make extensive use of floating-point arithmetic. Due to the complexity and expense of the floatingpoint hardware, these algorithms are usually converted to fixed point operations, or implemented using floating-point emulation in software. This study presents the design and implementation of custom floating-point units...

Floating point operations in digital systems form an integral part in the design of many digital processors. Digital Signal Processor is the most important application of floating point operations. In the recent years many approaches for floating point operations have been proposed and their merits and demerits are compared. For floating point operations the operands are first converted into IE...

Today’s digital signal processing applications such as radar, echo cancellation, and image processing are demanding more dynamic range and computation accuracy. Floating-point arithmetic units offer better precision, higher dynamic range, and shorter development cycles when compared to fixed-point arithmetic units. Minimizing the design’s time to market is more important than ever. Algorithm de...

a method based on the ultrasound-assisted solidification of floating drop microextraction technique was developed for the spectrophotometric and spectrofluorimetric determination of curcumin in turmeric powder. in this work a small volume of an organic solvent was floated on the surface of an aqueous solution. after sonication the organic solvent is solidified and separated. the effect of extra...

Floating matrix tablets are designed to prolong the gastric residence time after oral administration, at a particular site and controlling the release of drug especially useful for achieving controlled plasma level as well as improving bioavailability. With this objective, floating dosage form containing clarithromycin as drug was designed for the treatment of Helicobacter pylori. Tablets conta...

Commercial applications and databases typically store numerical data in decimal format. Currently, however, microprocessors do not provide instructions or hardware support for decimal floating-point arithmetic [ 1 ]. Consequently, decimal numbers are often read into computers, converted to binary numbers, and then processed using binary floating-point arithmetic. Results are then converted back...

Floating roofs are widely used to store petroleum products with high volatility. This is to prevent the product loss and to ensure safe environment around the storage tanks. However, small number of researches were accomplished. These researches aim at study the design of the floating roof and the associated risks that it faces during operation. In an effort to compensate the lack of knowledge ...

Floating-point processing utilizes a format defined in IEEE 754, and is supported by microprocessor architectures. However, the IEEE 754 format is inefficient to implement in hardware, and floating-point processing is not supported in VHDL or Verilog. Newer versions, such as SystemVerilog, allow floating-point variables, but industry-standard synthesis tools do not support floating-point techno...

the objective of this work was to develop and evaluate the levofloxacin hemihydrate floating formulations (f1-f9). selection of optimized batch was done by model dependent approach and novel mathematical approach. f1-f9 batches were prepared by direct compression method using gelucire 43/01 (hydrophobic) and hydroxypropylmethylcellulose (hydrophilic) polymer in different ratios. the floating ta...
