Finite field polynomial euclidean algorithm
WebTwo implementation techniques: (1) pure combinational logic, and (2) finite state machine with data-path (FSMD), are used to implement the classical Euclid’s algorithm and the SPX algorithm. Webpolynomials (if you have only seen the euclidean algorithm over the integers, check that the natural analog to the Euclidean algorithm for the integers works equally well in polynomial rings over arbitrary fields, where the remainder is then a polynomial of …

WebDec 9, 2013 · Even if the inputs u and f are coprime, the extended Euclidean algorithm is only guaranteed to generate v, w such that vu+wf=r where r is a polynomial of degree 0 -- not necessarily the multiplicative unit. You must multiply v by 1/r (considered as an element of F) in order to get the multiplicative inverse of u.
