  • Abstract
    A generalized version of the plus-minus algorithm is used for implementing dividers over GF(pn). Generic dividers have been synthesized in the general case of GF(pn) and in the particular cases of GF(2n) and GF(p). The theoretical costs are O(logN) being N the number of field elements, and the theoretical computation times are O(logN) in the case of dividers over GF(pn) and GF(2n), and O((logN)2) in the case of dividers over GF(p). Finally, the results of FPGA implementations are reported, and a comparison is made between dividers over GF(p), GF(2n) and GF(pn).
