A Parallel multiplier using approximate compressors are proposed in this paper. The two new approximate 4-2 compressors are proposes that the simplified compressors have better power consumption than the optimized 4-2 compressor existing designs. These approximate compressors are then used in the restoration module of a Parallel multiplier. Four different schemes for utilizing the proposed appr...

Multiplying floating point numbers is a critical requirement for DSP applications involving large dynamic range. This paper focuses only on single precision normalized binary interchange format targeted for Xilinx Spartan-3 FPGA based on VHDL. The multiplier was verified against Xilinx floating point multiplier core. It handles the overflow and underflow cases. Rounding is not implemented to gi...

Interval arithmetic provides an e cient method for monitoring and controlling errors in numerical calculations. However, existing software packages for interval arithmetic are often too slow for numerically intensive computations. This paper presents the design of a multiplier that performs either interval or oating point multiplication. This multiplier requires only slightly more area and dela...

We present an architecture of a high performance decision feedback equalizer based on a computation sharing multiplier. The computation sharing multiplier (CSHMR) uses a redundant number scheme and targets removal of computational redundancy by computation re-use. Use of CSHMR leads to high performance FIR filtering operation by re-using optimal precomputations. A decision feedback equalizer (D...

In this paper, we investigate the structure of the multiplier module of a Hilbert module over a locally C∗-algebra and the relationship between the set of all adjointable operators from a Hilbert A -module E to a Hilbert A module F and the set of all adjointable operators from the multiplier module M(E) of E to the multiplier module M(F ) of F.

Abstract  This paper presents a design for a reconfigurable multiplier array. The multiplier is constructed using an array of 4 bit Flexible Array Blocks (FABs), which could be embedded within a conventional FPGA structure. The array can be configured to perform a number of 4n x 4m bit signed/unsigned binary multiplications. We have estimated that the FABs are about 35 times more efficient in ...

Using good properties of an optimal normal basis of type I in a finite field F2m , we present a design of a bit serial multiplier of Berlekamp type, which is very effective in computing xy. It is shown that our multiplier does not need a basis conversion process and a squaring operation is a simple permutation in our basis. Therefore our multiplier provides a fast and an efficient hardware arch...

As the complexity of digital filters is dominated by the nuniber of multiplications, many works have focused on minimizing the complexity of multiplier blocks that compute the constant coefficient niultiplications required in filters. Although the complexity of multiplier blocks is significantly reduced by using efficient techniques such as decomposing multiplications into simple operations and...

ÐThe Massey-Omura multiplier of GF …2m† uses a normal basis and its bit parallel version is usually implemented using m identical combinational logic blocks whose inputs are cyclically shifted from one another. In the past, it was shown that, for a class of finite fields defined by irreducible all-one polynomials, the parallel Massey-Omura multiplier had redundancy and a modified architecture o...
