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).
