system C源码 一种替代verilog的语言

      s OP u -> u                        s OP u -> s
      u OP s -> u                        u OP s -> s
      s OP s -> s                        s OP s -> s

      u OP un = un OP u -> u             u OP un = un OP u -> u
      u OP sn = sn OP u -> u             u OP sn = sn OP u -> s

      s OP un = un OP s -> s             s OP un = un OP s -> s
      s OP sn = sn OP s -> s             s OP sn = sn OP s -> s

    In the new semantics, the result is u if both operands are u; the
    result is s otherwise. The only exception is subtraction. The result
    of a subtraction is always s.

    The old semantics is like C/C++ semantics on integer types; the
    new semantics is due to the VSIA C/C++ data types standard.
