    core.Adder: fix timing by using Z_{2^{32}} arithmetics · 79ae3d38

    An addition is trivially synthesized to a ripple-carry adder. With
    512b + 512b the carry chain is super long and delay becomes super
    high. Although the results are same, now just use 16 32b ripple-
    carry adders, which is also what the standards specify. Later a
    faster adder may be considered.
