--- Comment #8 from dmitry.selyutin at 3mdeb.com ---
So, to summarize, does the following work for us?

    dc[16] = [0]*16
    do i = 0 to 15
        temp <- (0b0 || RA[4*i:63]) + (0b0 || RB[4*i:63])
        dc[i] <- temp[0]
    c <- ([dc[0]]*4 || [dc[1]]*4 || [dc[2]]*4 || [dc[3]]*4 ||
            [dc[4]]*4 || [dc[5]]*4 || [dc[6]]*4 || [dc[7]]*4 ||
            [dc[8]]*4 || [dc[9]]*4 || [dc[10]]*4 || [dc[11]]*4 ||
            [dc[12]]*4 || [dc[13]]*4 || [dc[14]]*4 || [dc[15]]*4)
    RT <- (¬c) & 0x6666_6666_6666_6666
