NEW APPROACH OF SIGNED BINARY NUMBERS MULTIPLICATION AND ITS IMPLEMENTATION ON FPGA

Multiplication of Signed-digit Numbers

A recently proposed technique for common-multiplicand multiplication of binary numbers is shown to be applicable to signed-digit numbers. We prove that multiplication of a single k-bit multiplicand by n k-bit multipliers can be performed using 0:306nk additions for canonically recoded signed-digit numbers, while the binary case requires 0:375nk additions.

A New Double Point Multiplication Method and its Implementation on Binary Elliptic Curves with Endomorphisms

Efficient and high-performance implementation of point multiplication is crucial for elliptic curve cryptosystems. In this paper, we present a new double point multiplication algorithm based on differential addition chains. We use our scheme to implement single point multiplication on binary elliptic curves with efficiently computable endomorphisms. Our proposed scheme has a uniform structure a...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
