Superscalar Pipelining Architecture and Multi-Pipeline Scheduling Policies

In this paper, we present the process of pipelining using superscalar processor. A super-scalar processor is one that is capable of sustaining an instruction-execution rate of more than one instruction per clock cycle. Maintaining this execution rate is primarily a problem of scheduling processor resources (such as functional units) for high utilization. Multiple pipes are used for improving the performance of pipelining. A superscalar processor can be envisioned having multiple parallel pipelines, each of which is processing instructions simultaneously from a single instruction thread.
