2. superscalar - Adjective
Meaning
superscalar (not comparable)
(computing, of a CPU architecture) Implementing instruction-level parallelism within a single processor, thereby allowing faster throughput than would otherwise be possible at the same clock speed.
superscalar (plural superscalars)
A superscalar processor, architecture or pipeline.

Examples
Best-case scenario (or peak) IPC rates in very superscalar architectures are difficult to maintain since it is impossible to keep the instruction pipeline filled all the time.
Both have a very similar superscalar in-order dual instruction pipeline configuration, and an instruction decoder which breaks down complex instructions into simpler ones before execution.
Both simple pipelining and superscalar design increase a CPU's ILP by allowing a single processor to complete execution of instructions at rates surpassing one instruction per clock cycle.
A multi-core superscalar processor is classified as an MIMD processor (Multiple Instruction streams, Multiple Data streams).
A superscalar processor can execute more than one instruction during a clock cycle by simultaneously dispatching multiple instructions to different execution units on the processor.
A superscalar processor is a mixture of the two.
