superscalar

A superscalar CPU architecture implements a form of parallelism called instruction-level parallelism within a single processor. It thereby allows faster CPU throughput than would otherwise be possible at the same clock rate. A superscalar processor executes more than one instruction during a clock cycle by simultaneously dispatching multiple instructions to redundant functional units on the processor. Each functional unit is not a separate CPU core but an execution resource within a single CPU such as an arithmetic logic unit, a bit shifter, or a multiplier.
