ABSTRACT = {The benefit of high radix Booth encoders in reducing the
number of partial products in fast multipliers has been hampered by the
complexity of generating the hard multiples. The use of redundant
binary (RB) Booth encoder can overcome this problem and avoid the error
compensation vector but at the cost of doubling the number of RB
partial products. This paper presents a novel covalent RB Booth encoder
to generate a compound RB partial product from two adjacent Booth
encoded digits. The new encoder fully exploits the characteristics of
Booth encoded numbers to restore the effective partial product
reduction rate of RB Booth encoder while maintaining the simplicity of
hard multiple generators and eliminating the constant correction
vector. A legitimate comparison on an $8 \times 8$-bit RB multiplier
prototype shows that the multiplier constructed with our proposed Booth
encoder consumes lower power and computes faster than those with the
normal binary and redundant binary Booth encoders.}

ABSTRACT = {This paper presents a complete error analysis for a novel
square root hardware implementation. The analysis includes the powering
method used for the initial approximation and the higher order
Newton-Raphson square root iterations. Both theoretical and algorithmic
error analysis are presented and compared. The algorithmic analysis
provides a more accurate error estimate which reduces the size of the
memory required in the initial approximation stage to less than half its
original size. }

ABSTRACT = {Elementary and high-level functions can be computed
in hardware using polynomial approximation techniques.
There are many techniques in the literature to calculate the
coefficients of such polynomials. Remez algorithm [1] provides
the optimal polynomial in the Chebyshev sense that is minimizing
the maximum error (minimax approximation).
This paper presents an algorithm for truncating the coefficients
of the minimax polynomials obtained from Remez algorithm
using an algorithmic method. A gain of 3 and 4 bits of accuracy
over the direct rounding is reported.
Muller [2] addressed the same problem but his algorithm is
applicable for the second order polynomials only. This paper
presents an algorithm that is applicable for any order.}

ABSTRACT = { This paper develops an efficient algorithm for the
computation of the square root operation. We propose a high order
Newton-Raphson algorithm for the computation of the square root
reciprocal. We also propose a more accurate algorithmic error
analysis for the initial approximation algorithm.
The double precision result is correctly rounded and we present an
error analysis for the algorithm.
The similarity between the multiplicative algorithms for the square
root and the divison allows the integration of the two operations
in a single unit. Our architecture uses a fused
multiply add unit (FMA) and implements the four IEEE rounding modes.
A VHDL model of the square root algorithm passes successfully a
functional testing composed of two million random test vectors.}
