superscalar
     
         A superscalar architecture is a {uniprocessor}
        that can execute two or more {scalar} operations in parallel.
        Some definitions include {superpipelined} and {VLIW}
        architectures; others do not.  Superscalar architectures
        (apart from superpipelined architectures) require multiple
        {functional unit}s, which may or may not be identical to each
        other.  In some superscalar processors the order of
        instruction execution is determined statically (purely at
        compile-time), in others it is determined dynamically (partly
        at run time).
