What is Superscalar?
A processor design that issues and executes several instructions per clock cycle. It has multiple execution units and processes independent instructions in parallel.
Field: CPUs and architecture
Superscalar in the explanations
A superscalar processor has multiple execution units and issues several independent instructions per clock, pushing IPC above 1.
What is the processor design called that issues and execute…CPI below 1 reflects superscalar execution of multiple instructions per clock.
