instruction scheduling
     
        The {compiler} phase that orders instructions on a
        {pipelined}, {superscalar}, or {VLIW} architecture so as to
        maximise the number of function units operating in parallel
        and to minimise the time they spend waiting for each other.
     
        Examples are filling a {delay slot}; interspersing
        {floating-point} instructions with integer instructions to
        keep both units operating; making adjacent instructions
        independent, e.g. one which writes a register and another which
        reads from it; separating memory writes to avoid filling the
        {write buffer}.
