Usually Euclid's algorithm, which computesgcd(a,b)gcd(a,b), is implemented as follows: whileb!=0:a%=b swap(a,b)returna Or, in recursive fashion, ifb==0:returnaelse:returngcd(b%a,b) While it works inO(n)O(n)time (wherennis the maximum of binary lengths ofaaandbb— that is,...
We present a new GCD algorithm for two integers that combines both the Euclidean and the binary gcd approaches. We give its worst case time analysis and we prove that its bit-time complexity is still O ( n 2 ) for two n-bit integers in the worst case. Our preliminar experiments show ...
This IC is known as Built in Self Test(BIST).In thispaper , we are particularly concentrating upon finding thecomparative parameters of Euclid's and Stein's Algorithm ,which is used to find greatest common divisor(GCD) of two nonnegative integers. Thus, the best parameters to be found can...
