We present algorithms that solve the following problem: given three ranges of floating-point numbers Rx, Ry , Rz , a floating-point operation (op), and a rounding-mode (round), generate three floating-point numbers x̄, ȳ, z̄ such that x̄ ∈ Rx, ȳ ∈ Ry , z̄ ∈ Rz , and z̄ = round(x̄ op ȳ). This problem, although quite simple when dealing with intervals of real numbers, is much more complex when consider...

OVERVIEW FPGAs are increasingly used as parallel processing engines for demanding digital signal processing applications. Benchmark results show that on highly parallelizable workloads, FPGAs can achieve higher performance and superior cost/performance compared to digital signal processors (DSPs) and general-purpose CPUs. However, to date, FPGAs have been used almost exclusively for fixed-point...

Engineers targeting DSP to FPGAs have traditionally used fixed-point arithmetic, mainly because of the high cost associated with implementing floating-point arithmetic. That cost comes in the form of increased circuit complexity and often degraded maximum clock performance. Certain applications demand the dynamic range offered by floating-point hardware but require speeds and circuit sizes usua...

A system for the rapid prototyping of floating point hardware designs is presented. This system, called Float, consists of a floating point class for the simulation of quantization effects associated with low precision floating point operators; an optimizer which can automatically determine the minimal number of exponent and fraction bits required for a specified degree of accuracy; and a param...

this paper examined the charge of circulating assets in common law jurisdiction. the aim was to know the way and basis that it is constituted and to find out its profits for creditors and also to find out its meaning and its impacts in market. the conclusion was that floating charge provides an appropriate security and benefits for the chargee and chargor, where chargee can achieve his benefits...

In this paper we present a design for a floating point unit partially compliant with the IEEE 754 floating point standard. The unit fully implements comparisons and partially implements floating-point addition and multiplication. It is fully parametrized and may be used with floating point numbers whose composite fields have widths of any desired length.

a multiple-unit oral floating system was prepared using the emulsification-solvent diffusion method to prolong the gastric emptying time of theophylline. for this purpose, theophylline, ethyl cellulose and dibutyl phthalate were dissolved in an ethanol/dichloromethane mixture, added to 0.1 m hcl containing nacl (20%) or saturated theophylline and/or different concentrations of polysorbate 80 an...

Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...

In this research, the effect of bubble surface area flux, Sb, and particle size on flotation rate constant, k, of pyrite (FeS2) particles was studied using bubble-particle interactions. The bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. The k increased with increase in the collision efficiency and decreas...
