Area-Efficient Evaluation of Arithmetic Expressions
Using Deeply Pipelined Floating-Point Cores
It has become possible to implement floating-point cores on FPGAs in an effort to
provide hardware acceleration for the applications that require high performance floating-point arithmetic.Due to this deep pipelining requirement and the
complexity of floating-point arithmetic, floating-point cores use
a great deal of the FPGA s area. an
area-efficient architecture and algorithm for the evaluation of
arithmetic expressions is described ....etc

Many scientific programs exchange large quantities of double-precision data between processing nodes and with mass storage devices. Data compression can reduce the number of bytes that need to be transferred and stored. However, data compression is only likely to be employed in high-end computing environments if it does not impede the throughput. This paper describes and evaluates FPC, a fast lossless compression algorithm for linear streams of 64-bit floating-point data. FPC works well on hard-to-compress scientific data sets and meets the thr ....etc

Floating-Point FPGA: Architecture and Modeling
An architecture for a reconfigurable device that is specifically optimized for floating-point applications is described in this article. The control logic and bit-oriented operations are implemented by the fine grained units and the parameterized and reconfigurable word-based lookup tables etc are implemented by the coarse grained units. These implement the lookup tables and the floating point operations as well as to implemen the data paths. the virtual embedded block scheme is described w ....etc

Abstract
This research paper presents techniques for solving the Arithmetic
problems related to number systems. In this work a Floating-point
arithmetic unit, including following functions: addition, subtraction,
multiplication, division, square root and conversion of integer to
floating-point and conversion of floating-point to integer, is designed.
Further it is shown how these functions can be implemented, and how
these functions can be verified.
Here in this research paper it is tried to redesign the floating-point unit.
It include ....etc

Prenormalization Rounding in IEE Floating-Point Operations Using a Flagged Prefix Adder,
This paper demonstrates howIEE 754 floating-point standard compliant rounding can be merged with carry-propagate addition in floating-point unit (FPU) designs by using a novel adaptation of the prefix adder. The paper considers add/subtract, multiply, and SRT divide operations and demonstrates that in every case a generic rounding architecture based on a prefix adder with a small amount of additional logic is sufficient to cover all the rounding modes. Cr ....etc

FFT/IFFT Block Floating Point Scaling



Introduction

The Altera FFT MegaCore function uses block-floating-point (BFP)
arithmetic internally to perform calculations. BFP architecture is a
trade-off between fixed-point and full floating-point architecture.
Unlike an FFT block that uses floating point arithmetic, a
block-floating-point FFT block does not provide an input for exponents.
Internally, a complex value integer pair is represented with a single scale
factor that is ....etc
