superscalar

   <architecture> 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 units}, 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).
