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).
