This paper describes a method for customising the representation of floating-point numbers that exploits the flexibility of reconfigurable hardware. The method determines the appropriate size of mantissa and exponent for each operation in a design, so that a cost function with a given error specification for the output relative to a reference representation can be satisfied. Currently our tool,...

Rapid Serial Visual Presentation (RSVP) is an effective tool for information navigation. We applied RSVP to the increasingly important task of image browsing. In total nine RSVP interfaces were developed, implementing three RSVP modes and three control sets. An evaluation was carried out to investigate the effect of RSVP mode and control set on image retrieval time. Subjective measures were als...

Abstract Wave energy converters (WEC) have been researched extensively to harvest large amounts of untapped ocean renewable energy. Floating-type point absorbers are a type WEC that converts the wave electrical energy, by utilizing relative motion multi-body system mainly consisting floating section and reaction section. The design floating-type is not straightforward needs special attention un...

Introduction Implementation of floating point in FPGA (Field Programmable Gate Arrays) is not easy. Paper presents FPGA core implementing these operations by representation of floating point numbers as 32-bit integer (fixed point) logarithm [1]. Basic arithmetical operations are performed in the logarithm numbering system (LNS) suitable for FPGA. Implemented intellectual property core takes jus...

We improve the well-known Wilkinson-type estimates for the error of standard floating-point recursive summation and dot product by up to a factor 2. The bounds are valid when computed in rounding to nearest, no higher order terms are necessary, and they are best possible. For summation there is no restriction on the number of summands. The proofs are short by using a new tool for the estimation...

an oral sustained-release floating tablet formulation of metformin hcl was designed and developed. effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and hpmc-peo polymer combination, respectively. tablet composition was optimized by response surface methodology (rsm). seventeen (17) trial formulations were analyzed according to box-behnken desi...

This project revolves around the design and implementation of floating point adder architecture using reversible logic to improve the design in terms of the number of garbage outputs and the number of gates used. In recent years, reversible logic has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology and optical computing because of it...

The design of CMOS based low pass filter for analog-to-digital, digital-to-analog and audio applications is described in this paper. Active load resistor and floating inductor is used for the implementation of low pass filter. CMOS technology has become dominant over bipolar technology for analog circuits design in mixed signal system. The differential floating active inductor is designed with ...

Transparency can be used to increase the visibility of a user’s workspace in situations where the space is obscured by floating windows and tool palettes. Dynamic transparency takes this approach further by making components more transparent when the user’s cursor is far away. However, dynamic transparency may make palettes and floating windows more difficult to target. We carried out a study t...

Showing new levels of high-performance, high-density, IEEE754-compliant floating-point applications in FPGAs is the focus of this white paper. A new tool is introduced that will allow 100 percent of the floating-point capability of the FPGA device to be used. Combined with the rich DSP resources and advanced routing fabrics of the most recent Altera® FPGAs, unprecedented performance numbers are...
